Three generations of leptons and quarks correspond to the lepton charges (LC) in the present work. Then, the leptons have the electric charges (EC) and lepton charges (LC) [1,2,3,4]. And the rest mass of 1.4 TeV/c^2 is assigned to the Le particle (new heavy lepton) with the EC charge of -2e based on the cosmic-ray electron/positron data of DAMP (Dark Matter Particle Explorer) and the cosmic...

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...

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...

Thanks to the historical detection of gravitational wave radiation from binary black hole and binary neutron star systems, the Virgo and LIGO observatories have enabled a revolutionary new channel to observe the Universe. The handful of very first, sensational observations have already provided precious new information relevant to astronomy, astrophysics, cosmology and fundamental physics,...

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...

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...

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. We develop the multiple scattering expansion
fro incoherent...

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...

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...

NOvA is a long-baseline neutrino oscillation experiment using Fermilab's 700 kW NuMI muon neutrino beam. Two functionally identical scintillator detectors are placed off the beam axis, separated by 810 km oscillation baseline. Both detectors have high active material fractions and are finely segmented allowing for precise identification and analysis of neutrino interactions. By observing both...

Events of dissociation of relativistic nuclei in nuclear track emulsion (NTE) allow a holistic investigation of “cold” ensembles of lightest nuclei. So far, with regard to fine structure dissociation of relativistic nuclei, the NTE technique remains the only means providing unique completeness of such observations at the best angular resolution and as well as a sufficient statistical...

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.
The Mainz Microtron MAMI is one of the main world facility for investigations in this energy region due to the presence of the high-intensity linearly and circularly polarized photon beams, recoil polarimeters, $4\pi$ calorimeter for detection of...

Muonium is a hydrogen-like atom consisting of a positive muon and an electron. It is an ideal two-body leptonic system, so it is possible to verify bound-state theory precisely. The muonium ground state hyperfine structure (HFS) can be used to extract fundamental constants: the muon-electron mass ratio and muon-proton magnetic moment ratio. In particular, muon-proton magnetic moment ratio is...

Scintillation detectors (SDs) based on organic plastic scintillators and optical fibers are among of the basic detectors at all modern accelerators and in astrophysics and neutrino experiments. In recent years, interest in SDs has increased significantly due to the forthcoming large-scale Updates of LHC, the construction of new accelerators NICA, FAIR, FCC, etc. At the same time, requirements...

The ALICE experiment is dedicated to study the hot and dense nuclear matter created in heavy ion collisions at the Large Hadron Collider. A crucial part of the ALICE physics programme is to study small colliding systems like proton-proton and proton-lead collisions and compare them with heavy ion collisions in order to disentangle effects coming from individual nucleon-nucleon interactions or...

The MEG experiment took data at the Paul Scherrer Institute in the years 2009-2013 and published the most stringent limit on the charged lepton flavor violating decay $\mu \rightarrow e \gamma$: BR($\mu \rightarrow e \gamma$) $<4.2 \times 10^{-13}$ $@90\%$ C.L.
The MEG detector is currently being upgraded in order to reach a sensitivity of $\sim 5 \times 10^{-14}$, which corresponds to an...

After the discovery of the Higgs boson in summer 2012, the understanding of its properties has been a high priority of the ATLAS and CMS physics programmes. Measurements of the Higgs boson mass, coupling constants and cross-sections are presented, based on the pp collision data acquired at 13 TeV. The analyses in several decay channels will be described and the results of the combination of...

T2K is a long-baseline experiment which has been designed to measure neutrino oscillations.
A high intensity beam of muon neutrinos or anti-neutrinos is produced at the J-PARC accelerator complex
and sent towards the near detector station (280 meters away from the neutrino source) and the far detector Super-Kamiokande (295 km).
The change in the measured intensity and composition of the...
