These rare half-lepton modes of B-meson decay are studied in electron-positron collisions on the SuperKEKB collider (KEK Research Center, Japan) with the highest luminosity in the world. The aim of this work is to find evidence of the manifestation of the influence of charged Higgs bosons in semipleptonic town decays. Research methods: conducting experiments on the electron-positron collider SuperKEKB, corresponding to Monte Carlo simulations of events and their comparison. The process e + e− → D + s D * s0 (2317) −X was analyzed for the first time. The results were obtained on complete sets of Belle experimental data collected at the energy in the center of mass ϒ (nS), n = 1, ..., 5, which corresponds to the integrated luminosity of 926 fb −1. Reconstruction of the decay B + → D ** 0π−, D ** 0 → D * −π +, D * - → D0π- s, where the decay of D0 was considered in three modes: K − π +, K − π + π + π− and K − π + π0). The formation of X (3872) and ψ (2S) in proton-antiproton collisions at energy in the system of the center of mass of 1.96 TeV on the Tevatron collider was studied. We co-authored the discovery in physics, a joint team of CERN and Fermilab, of Oderons, particles that do not contain quarks. The branching coefficient of decay B− → D0ℓ − ν¯ℓ was measured using 62.8 fb − 1 BelleII data. The most accurate measurements of the lifetime of D0 and D + mesons in the world were performed. He took an active part in the development of experimental tools, as well as in modeling and measurements on test beams for future experiments. Elastic and inelastic scattering have been experimentally studied heavy ions by light and heavy nuclei.  Product Description popup.authors Gogota Olha P Horbachenko Oleksandr М. Dudar Bogdan V.
