DANSS is a one cubic meter highly segmented solid scintillator detector. It consists of 2500 scintillator strips (100x4x1 cm3), covered with gadolinium loaded reflective coating and read out with SiPMs via wave length shifting fibers. Groups of 50 strips are also read out by conventional PMTs. The detector does not contain dangerous liquids and therefore has no safety restrictions on location clos ... More

The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to directly measure the absolute neutrino mass scale from the kinematics of tritium beta-decay with an unprecedented sensitivity of 200 meV (90%CL). A nonzero neutrino mass reduces the endpoint energy and distorts the spectrum, especially in the vicinity of this endpoint. Thanks to the high source luminosity and stability KATRIN has th ... More

The methods of the fractal geometry are applied to the particles distribution for the multiparticle events from heavy-ion collisions (HIC). It is shown that such kind of analyses provides a possibility to distinguish between different equation of state in hydrodynamic models of HIC. Implementation of these methods could reveal many other features of the physics for particle production.

We interpret asymmetries for $D^+ D^-$ and $D_s^+ D_s^-$, as observed recently by the LHCb collaborations in terms of subleading quark/antiquark fragmentation. The related conclusions for lower collision energies as well as for production of high-energy neutrinos in the Earth's atmosphere will be presented.

A new giant electron-positron collider, operating at energy frontier, is a natural proposal in order to push particle physics into new regime of precise measurements, in particular in the sectors of electroweak observables and Higgs boson parameters. The four projects of such accelerators: two linear (ILC and CLIC) and two circular (FCC and CEPC) are currently in various stages of development. Th ... More
At future e+e- colliders integral luminosity will amount to several ab-1 to provide the needed statistics for precision physics measurements (both SM and BSM). New measurements which will be possible with large statistics and high energies accessible at the future e+e- colliders would allow detailed study of the CR phenomenon, specially in the hadronic $WW$ decays, and would be help for other st ...

In the wake of the recent measurements of the decays $B_c\to J/\psi\,\pi(K)$ and $B_c\to J/\psi\,\ell\nu_\ell$ reported by the LHCb Collaboration we calculate the form factors for the $B_c\to J/\psi$ and $B_c\to \eta_{c}$ transitions in full kinematical region within covariant confined quark model.

Within the framework of the Mellin transform method we investigate the effective contours that allow to accelerate a numerical computation of Mellin-Barnes (MB) integrals significantly. We consider the case of a finite asymptotic behavior of the contour of the stationary phase, which start at the saddle point, in the limit Re(z) tends minus infinity. The MB integrals arising for the nonsinglet ... More

In spite of the fact that nuclear track emulsion (NTE) was developed more half a century ago, it still remains a universal and cost-efficient detector. The application of NTE is especially well grounded where tracks of nuclear particles cannot be reconstructed using electronic detectors. At the JINR Nuclotron the BECQUEREL experiment [1] is performed a program of irradiation of NTE stacks in the b ... More

Recently there has been much interest in the exclusive and semiexclusive production of vector mesons in nucleus-nucleus collisions at the LHC. These processes are induced by the strong electromagnetic field of one of the ions. The relevant subprocesses are the coherent and incoherent diffractive photoproduction mechanisms.

Session: Introduction
Presented by Prof. Mikhail ITKIS on 25 Sep 2018 at 09:05
We suggest a renewed view on non-renormalizable interactions treated perturba- tively within a kinematically dependent renormalization procedure. It is based on the usual BPHZ R-operation which is equally applicable to any local QFT indepen- dently whether it is renormalizable or not. The key point is that the renormalization constant becomes the function of kinematical variables acting as an oper ... More

Until 2010, the accepted value for the proton charge radius was 0.8768 ± 0.0069 fm. This was determined from both electron-proton scattering and electron hydrogen spectroscopy. In 2010 the Proton Radius Puzzle (PRP) began when the CREMA Collaboration determined the proton radius via muonic hydrogen spectroscopy, yielding a value 7σ smaller that the previous result (0.84184 ± 0.00067 fm). One p ... More

A number of features of the Run 1 data impelled us to hypothesize the existence of a heavy boson with a mass around 270 GeV that decays predominantly into Sh, where h is the SM Higgs boson and S is an additional, lighter boson. A number of predictions are made. This includes the anomalous production of opposite sign di-leptons, same sign di-leptons, three and more leptons. These multi-lepton final ... More

In recent years, many data show the presence of exotic states at low energies, below 2 GeV. Some authors claim about a signature of a new physics.

In particular, muon-proton magnetic moment ratio is used ... More
