This work is devoted to the search for a hypothetical heavy sterile neutrino N on CMS data at the Large Hadron Collider, where N is born in the decay of a D+s meson with a violation of the lepton number D+s→μ+N→μ+μ+π-, and the source of D+s mesons are semilepton decays B0s→D+sμ−vˉμ. Studies of Monte Carlo simulations of signal decay modeled under CMS detector conditions are presented. Several possible points in the parameter space of a heavy neutrino (mN,|VμN|2) have been generated and studied, where mN and |VμN|2 are the mass and the mixing parameter, respectively.The kinematic and topological parameters involved in particle decay were studied, and the efficiency of the generator and reconstruction were evaluated. The results obtained will be used for the subsequent search for the decay of D+s→µ+N on CMS data.
