  • B-tagging and searches for new physics beyond the standard model 
    Obikhod, T.V.; Petrenko, E.A. (Вопросы атомной науки и техники, 2020)
    The article is devoted to the searches for new particles predicted by physics beyond the Standard Model through the b-tagging algorithm. The dependence of b-tagging efficiency on the jet identification, impact parameter ...
  • Computer modeling of tth(H) Higgs boson production with MSSM model 
    Obikhod, T.V.; Petrenko, I.A. (Problems of Atomic Science and Technology, 2022)
    We studied the properties of the MSSM Higgs bosons, h and H through the decay into b-quarks in associated production with a top-quark pair. There was used the tree-level Higgs sector described by two parameters MA and tanβ ...
  • Decay width modeling of Higgs boson within THDM model 
    Obikhod, T.V.; Petrenko, E.A. (Вопросы атомной науки и техники, 2021)
    As part of the search for new physics beyond the Standard Model, we chose the determination of the Higgs boson decay width as one of the least experimentally determined values. The decay widths into the four fermions of ...
  • High energy physics and algebraic geometry 
    Malyuta, Yu.M.; Obikhod, T.V. (2009)
    Superstring theory is applied to construction of the Minimal Supersymmetric Standard Model.
  • Investigations of electroweak symmetry breaking mechanism for Higgs boson decays into four fermions 
    Obikhod, T.V.; Petrenko, E.A. (Вопросы атомной науки и техники, 2020)
    Models with extended Higgs boson sectors are of prime importance for investigating the mechanism of electroweak symmetry breaking for Higgs decays into four fermions and for Higgs-production in association with a vector ...
  • NLO corrections to the pair production of supersymmetric particles 
    Obikhod, T.V.; Verbytskyy, A.A. (Вопросы атомной науки и техники, 2014)
    The analysis of recent experimental data received from LHC (CMS) restricts the range of MSSM parameters. Using computer programs SOFTSUSY, SDECAY the mass spectrum and partial width of superpatners are calculated. With the ...
  • Reconstruction of superpartner masses 
    Malyuta, Yu.M.; Obikhod, T.V. (Вопросы атомной науки и техники, 2011)
    In the context of Minimal Supersymmetric Standard Model histograms of mass distributions for superpartners are constructed.
  • Searches for superparticles at the LHC by application of computer simulation 
    Obikhod, T.V.; Malyuta, Yu.M. (Вопросы атомной науки и техники, 2013)
    The analys of recent experimental data received from LHC (CMS) restricts the range of MSSM parameters to the new five parameters. Using computer programs SOFTSUSY, SDECAY and PYTHIA the mass spectrum, partial width and ...
  • Searches for superparticles of CMSSM model at the LHC 
    Obikhod, T.V. (Вопросы атомной науки и техники, 2015)
    Using the discovery of a SM-like Higgs boson by ATLAS and CMS Collaborations and the observation by CMS and LHCb of BR(Bs → μ⁺μ⁻) decay as well as 8 TeV ATLAS 20 fb⁻¹ jets + ET data set we received an indirect constraint ...
  • Searches for SUSY at the LHC 
    Obikhod, T.V. (Вопросы атомной науки и техники, 2014)
    Searches for SUSY with R-parity conservation are connected with LSP particle - the best dark matter candidate. Using the new Minimal Supersymmetric Standard Model (MSSM) parameters received from recent experimental ...
  • Search for supersymmetry using final states with muons, jets, and missing transverse momentum with the CMS detector in √ s = 7 TeV pp collisions 
    Lukyanenko, S.T.; Obikhod, T.V. (Вопросы атомной науки и техники, 2015)
    The results of search for superparticles in final states with jets, muons and missing transverse energy are presented. The study is based on a data obtained in proton-proton collisions at √s = 7 TeV. They correspond to ...
  • Stringy approach to the Minimal Supersymmetric Standard Model 
    Malyuta, Yu.M.; Obikhod, T.V. (Вопросы атомной науки и техники, 2010)
    Superstring theory is applied to construct the Minimal Supersymmetric Standard Model. The mass spectrum, partial widths and production cross sections of superpartners are calculated. This approach gives concrete predictions ...
  • Studying the resonance production cross-section of the heavy vectors within Heavy Vector Triplet model 
    Obikhod, T.V.; Petrenko, I.A. (Problems of Atomic Science and Technology, 2023)
    In the context of TeV-scale extensions of the Standard Model both the experimental data and the construction of phenomenological models for the new heavy bosons searches are used by us. Heavy particles are predicted by the ...
