The work is devoted to the study of microscopic black hole production with the CMS experiment at LHC. One of the predictions of theoretical models with extra spatial dimensions and low-scale quantum gravity is the possibility of production of microscopic black holes in particle collisions, in particular, at colliders. Based on the simulation with the BlackMax and the Charybdis2 event...

Neutrino physics is a major part of modern science. Now in Dzhelepov Laboratory of Nuclear Problems of JINR, we are developing a global neutrino analysis software (GNA). The main goal of this program is to create some universal way to analyze any kind of neutrino experiments. At first, this problem has been being solved only for reactor neutrino experiments such as Day Bay, JUNO.

А direct search for the production of a Higgs boson in association with single top quark is performed. The analysis considers single top quark production via t channel and uses Higgs boson decays to a bottom quark-antiquark pair and semileptonic top quark decays. Such process is strongly suppressed in the Standard Model. An observation of this production mode would be an unambiguous indication...

The main goal of the NA62 experiment at CERN is a study of the ultrarare decay К+ → pi nu nu. The collected statistics allows to analyse other rare decays, in particular, К+→ mu nu mu mu. Rare decays make it possible to experimentally investigate one of the aspects of the Standard Model, the chiral perturbative theory (ChPT). ChPT predicts decay probability of К→ mu nu mu mu: 1.35 х 10^(-8)....

The inner part of the BESIII drift chamber is expected to be replaced with a cylindrical GEM (CGEM) tracker in summer 2019. Despite providing generally similar performance to the currently installed inner drift chamber, in may improve tracking of the low-momentum charged particles, which is strongly affected by the beam-induced background. Moreover, it can be seen as testing ground for...

We study angular correlations in associated hadroproduction of Υ(1S) with the D± and D0 mesons at the LHC in the Leading Order of the parton Reggeization approach.

Hadronization of a $\bar{b}b$-pair to Υ(1S) is described within the NRQCD-factorization framework. Production of D−mesons...
