14:30 Review of the CERN SPS heavy ion programmes

The talk briefly presents history, status, and plans of heavy ion programmes at the CERN SPS. The first measurements started in 1886 and they were concluded twenty years ago by the discovery of a new state matter. The second programme started in 1999 and led to observations of signals of the onset of deconfinement. The currently on-going programme is motivated by a possibility to discover the critical point of strongly interacting matter. An attempt to formulate priorities for future measurements which can be conducted, in particular, at JINR NICA — charm quarks versus the onset of deconfinement and detailed study of the onset of fireball — closes the talk.

09:25 Anisotropic collective flows and development of a technique for their measurement at the MPD facility of the NICA collider

RFBR grant 18-02-40086

The goal of this project is to develop and deploy experimental measurement techniques for the azimuthal collective flow measurement with the MPD experiment at the NICA collider for different types of hadrons produced in nucleus-nucleus collisions. As a result of the project implementation a numerical modelling of the anisotropic collective flow based on the modern Monte-Carlo event generators of heavy-ion collisions with subsequent simulation of the realistic response of the MPD detector subsystems based on the GEANT platform and reconstruction algorithms build in the MPDROOT will be performed. A set of simulated heavy-ions collisions will be used for deploying of the existing and development of new algorithms for the measurement of the anisotropic collective flow which will utilize different combinations of the MPD detector subsystems.

09:50 Investigation of the properties of strongly interacting matter at energies of the NICA collider using femtoscopy and factorial moments.

RFBR grant 18-02-40044
Aim of the project (No 18-02-40044) is to study the collective effects and dynamics of quark-hadron phase transitions using femtoscopic correlations of hadrons and factorial moments of particle multiplicity utilizing the Multi-Purpose Detector (MPD) experiment at NICA. The correlation femtoscopy allows one to measure the space-time characteristics of particle production processes due to the effects of quantum statistics and final state in reactions. We report on the study of the simulated Au+Au and Bi+Bi collisions using UrQMD and vHLLE at NICA energies.
Data analysis was performed using the software packages for femtoscopy and factorial moments analyses developed within the current project. The packages are integrated into the MPD software environment (MpdRoot).
The estimated pion and kaon three-dimensional femtoscopic radii were obtained for the vHLLE+UrQMD (hydrodynamics with the cross over and the first-order phase transitions with hadronic rescattering as an afterburner) and for the UrQMD models (hadron gas transport approach). The influence of the two-particle detector effects such as track-splitting and track-merging on the two-particle correlation functions will be presented. Estimated pion femtoscopic radii are compared with the measurements from the STAR experiment. The factorial moments of particle multiplicities is a sensitive tool to look for the evidence of the change in the type of the phase transition. The sensitivity of s called factorial moments of particle multiplicity on the initial conditions and properties of nuclear matter equation of state will be discussed.

10:15 BM@N data analysis of a single nucleon and two-nucleon Short Range Correlations in nuclei

RFBR grant 18-02-40046
I will review the current status of the project. I plan to emphasize the recent analysis of the quasi-free scattering of 48 GeV/c 12C ions from hydrogen, where the final and initial state interactions (FSI/ISI) are largely suppressed. The ground-state distribution of single nucleons is studied by detecting two protons at large angles in coincidence with an intact 11B nucleus. The 11B detection is shown to select the transparent part of the reaction and exclude the otherwise large ISI/FSI
contribution that would break the 11B apart. By detecting the residual 10B and 11Be nuclei, we further identified SRC nucleon-nucleon pairs, and establish the separation of the pair wave-function from that of the residual system. All measured reactions are well described by theoretical calculations that do not contain ISI/FSI. Following the completion of the first analysis phase, a paper was prepared for publication. We plan now to continue analyzing the triple coincidence events with a recoil neutron and to study multi-track events. This is plan in parallel to preparation for the next run.

09:25 The study of characteristics and calibration of the electromagnetic calorimeter for the NICA/MPD detector

RFBR grant 18-02-40079
The electromagnetic calorimeter is the important part of the NICA / MPD detector in terms of solving fundamental problems in studying of the nuclear matter properties. The high-granularity electromagnetic calorimeter (ECal) of the Multi-Purpose Detector (MPD) at heavy-ion NICA collider is optimized to measure the spatial coordinates and energy of photons and electrons. The production of the calorimeter modules was started this year. This report presents the methods and results of testing and calibration of the ECal modules. A technique for measuring assemblies of calorimeter modules on cosmic muons was developed, which allows calibrating a large number of modules in a wide dynamic range during limited time. For the simultaneous calibration of 12 modules for each of 8 types of modules a special stand was designed and manufactured. The periodic measurement to selective quality control and determination of the main physical parameters of modules was proposed to carry out on an electron beam at various energies. For this purposes, an electron beam of S-25P synchrotron of the Lebedev Physics Institute has been approved. A secondary electron channels was commissioned on the bremsstrahlung photon beam and transported to the calibration area. The calibration measurements were started at the beginning of 2020 with electron beam using an assembly of calorimeter modules at energies from 30 to 300 MeV. A higher electron beam energies are under tests. The simulation programs for beam and cosmic tests were developed. The experimental results in comparison with simulated data are presented and discussed. This work was supported by RFBR grants No. 18-02-40079.

14:00 Improvement of information systems for online and offline data processing of experimental installations of the NICA complex

RFBR grant 18-02-40125
Acquiring, storing, processing and analyzing of experimental and simulated data are an integral part of high-energy physics experiments. These tasks are of particular importance in the experiments of the NICA megaproject due to the high interaction rate and particle multiplicity of ion collision events, therefore the task of automating the considered processes for the NICA complex is a very urgent topic. The report is devoted to the development of new information systems as well as a set of convenient information services for collaboration members to automate the storing and processing data and information on the experiments. The Geometry Information System and Online Electronic Logbook, which are on the final stage of the implementation, are presented. In addition, the design of the Condition Database and Event Metadata System, which are scheduled to be completed next year, are described in detail. The developing systems provide storing information required for event processing and physics analysis and organize a transparent, unified access and data management throughout the life cycle of the scientific researches in the NICA megaproject. One of the key aspects, the integration of the information systems into the experiment workflow is also shown.

Theoretical model of the reaction $^{12}$C(p,2pN)$^{10}A$ is developed in the plane wave approximation assuming pole mechanism of quasi-elastic knock-out of the nucleon from the short-range correlated (SRC) NN-pair. Spectroscopic factors for two nucleons in a definte spin ($S$) and isospin ($T$) states in the $^{12}$C nucleus are calculated within the translationally-invariant shell model. High momentum part of the internal wave function of the NN-pair is replaced by the realistic wave function of the deuteron $(ST=10)$ or singlet ($^1S_0$) deuteron $(ST=10)$.Numerical calculations for distributions over momentum of the nucleon spectator and c.m. momentum of the NN-pair are performed at proton beam energy 4 GeV.

RFBR grant 18-02-40125
The report is dedicated to the Geometry Information System based on the Geometry Database, which is developed for the experiments of the NICA project. The feature of the NICA experiments is a similar approach to storing detector geometries and methods to use them, which employ ROOT or ASCII (.geo) formats and common interfaces of the FairRoot software developed by the FAIR collaboration. The main purpose of the system is to provide a centralized storage of detector geometries, which are actively used in detector simulation and data processing, convenient tools for managing geometry modules, and ensure versioning of the setup assemblies as a combination of the modules and additional support files. The unification of the Geometry Database allows to minimize the cost of creating and maintaining a geometry database for each experiment. The report shows the structure of the Geometry Database, access roles and its implementation features. An important part of any information system – interfaces, such as Application Programming Interface (API) and user-friendly Web interface, will be also presented.

Projected high volume and rate of data that will be collected and produced by SPD experiment requires a special strategy for the organization of data processing (computing). Experience and technology level reached during the organization computing for LHC experiments should be, at least, taken into account for new HEP experiments which will produce a significant amount of data.
In this talk, we are going to present the computing infrastructure for SPD experiment and describe an organization of a set of services that will help with the automation of data processing by managing data and calculation in a distributed environment.

17:50 Integration of distributed heterogeneous computing resources for the MPD experiment with DIRAC Interware

RFBR grant: 18-02-40101
Computing and storage resources are essential for effective Monte-Carlo generation. In JINR there are several different resources. Tier1 and Tier2 clusters, Govorun supercomputer, JINR Cloud, and NICA cluster as computing resources. EOS disk storage and dCache tape storage. To use all these resources individually users have to be aware of many details and differences between resources and keep track of load on all of them. DIRAC Interware was adopted, configured, and expanded to fulfill requirements to allow massive simultaneous Monte-Carlo generation for MPD. For a year the joint infrastructure was used via DIRAC to run successfully 380000 jobs with an average duration of 5 hours each. The use of DIRAC allowed unified data access, performance estimation, and accounting across all resources.

10:40 Fast data-driven readout system for the wide aperture Silicon Tracking System of NICA-BM@N experiment

RFBR grant 18-02-40047
BM@N experiment at Nuclotron is currently being upgraded in order to study the high-density nuclear equation-of-state in collisions between gold nuclei at beam energies 2– 4.5 AGeV. The measurement of high-multiplicity events at interaction rates up to 5 MHz requires the installation of four new tracking stations equipped with double-sided micro-strip silicon sensors, which have been developed for the CBM experiment at FAIR. Silicon Tracking System will comprise ~600 k channels with fast data driven readout electronics. Data acquisition system for the Silicon Tracking System of BM@N experiment should approve a new principle of data acquisition in a data driven mode, which will be used later in CBM. However, it should also operate with a trigger signal, provided by the trigger system of BM@N experiment. For this task a readout system, which is capable to work both in trigger and self-trigger modes and is adopted for the requirements of BM@N experiment, is developing in a close collaboration with CBM group.

16:00 Lattice study of the confinement/deconfinement phase transition in SU(3)-gluodynamics in rotating frames

RFBR grant 18-02-40126
The influence of the rotation on the confinement/deconfinement phase transition in SU(3)-gluodynamics was investigated using the Monte-Carlo lattice simulations. The calculations have been performed in rotating reference frame, where the rotation is introduced using an external gravitational field. To study the confinement/deconfinement transition the Polyakov loop and its susceptibility have been computed for various values of the temperature and angular velocity. The obtained results show that the critical temperature of the confinement/deconfinement phase transition in SU(3)-gluodynamics increases with a growth in the angular velocity. It is shown that this effect does not depend on the lattice size and boundary conditions used.

16:20 Phase diagram structure and kaon-to-pion ratios in the entanglement SU(3) PNJL model in Breit-Wigner and Beth-Uhlenbeck approaches

Within the three-flavor PNJL and EPNJL chiral quark models we have obtained pseudoscalar meson properties in quark matter at finite temperature $T$ and baryochemical potential $\mu_B$.
We compare the meson pole (Breit-Wigner) approximation with the Beth-Uhlenbeck (BU) approach that takes into account the continuum of quark-antiquark
scattering states when determining the partial densities of pions and kaons.
We evaluate the kaon-to-pion ratios along the (pseudo-)critical line in the $T-\mu_B$ plane as a proxy for the chemical freezeout line, whereby the variable
$x=T/\mu_B$ is introduced that corresponds to the conserved entropy per baryon as initial condition for the heavy-ion collision experiments.
We present a comparison with the experimental pattern of kaon-to-pion ratios within the BU approach and using $x$-dependent pion and strange quark potentials.
A sharp "horn" effect in the energy dependence $K^+/\pi^+$ ratio is explained by the enhanced pion production at energies above $\sqrt{s_{NN}}=8$ GeV, when
the system enters the regime of meson dominance.
This effect is in line with the enhancement of low-momentum pion spectra that is discussed as a precursor of the pion Bose condensation and entails the
occurrence of a nonequilibrium pion chemical potential of the order of the pion mass.
We elucidate that the horn effect is not related to the existence of a critical endpoint in the QCD phase diagram. in the QCD phase diagram.

The most interesting region of the QCD phase diagram lies close to the critical temperature at finite quark density. When the temperature is approaching the critical one from above the strong fluctuation regime sets in. We reveal and analyze the unusual behavior of the transport coefficients under the impact of fluctuations. These include the bulk viscosity, speed and attenuation of the sound, soft photon emissivity and some others.

17:40 Stability of shock waves in anisotropic hydrodynamics

Hot and dense hadronic matter created in the early stages of relativistic heavy-ion collisions has strong spatial anisotropy. The rapid expansion of matter along the beam-axis in the first moments after the collision leads to a strong drop in the ratio of longitudinal and transverse pressures. One of the hydrodynamic descriptions of such a system is the anisotropic approach, in which the anisotropy parameter is explicitly introduced for the one-particle distribution function.
The question of how to generate shock waves in a quark-gluon plasma is still open, but it is clear that they exist in such a medium, that is very well described by hydrodynamic equations. Shock waves are closely related to the jet quenching effect and hadronization; therefore, it is especially interesting to study them in the context of anisotropic system. Registration of shock waves in matter created in relativistic collisions of heavy nuclei directly depends on the degree of their stability. The stability of shock waves has not yet been studied for anisotropic hydrodynamics.
The purpose of this report is to highlight the problem of shock wave stability in anisotropic relativistic hydrodynamics. The influence of small perturbations on the behavior of the discontinuity surface will be considered, and the dependence of this behavior on the anisotropy parameter will also be studied.
