Wilson loops as probes of phase transitions and conductivity phenomena
Tetiana Obikhod, Ievgenii Petrenko
Wilson loops are among the most fundamental gauge-invariant observables in quantum field theory, encoding the global structure of gauge fields through their holonomy along closed c…
Studying the VBF Hjj and Hjjj Higgs Boson Production in QCD and EFT Theory
T. V. Obikhod, Ie. A. Petrenko
The discovery of the Higgs boson made it possible not only to study its physical properties and update its search strategies, but also to apply new theoretical constructs to explai…
Studying the resonance production cross-section of the heavy vectors within Heavy Vector Triplet model
T. V. Obikhod, I. A. Petrenko
In the context of TeV-scale extensions of the Standard Model both the experimental searches and the construction of phenomenological models for the new heavy bosons searches are us…
Computer modeling of Higgs boson production with MSSM model
Tetiana Obikhod, Ievgenii Petrenko
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 sect…
Searches for signal in the MSSM model
Tetiana Obikhod, Ievgenii Petrenko
We considered the new signature of a charged Higgs boson, , which is almost background free as the promising to study of supersymmetry…
Studying of final states in p-Au and p-Pb collisions
Tetiana Obikhod, Ievgenii Petrenko
In the framework of PYTHIA8.2 program we considered p-Pb and p-Au heavy ion collisions at the energy of 5.02 TeV and 8 TeV. The advantage of this program is in the combining of sev…
Decay width modeling of Higgs boson within THDM model
T. V. Obikhod, I. A. Petrenko
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…
Investigations of electroweak symmetry breaking mechanism for Higgs boson decays into four fermions
T. V. Obikhod, I. A. Petrenko
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-…
Probing approach of the Parton-Hadron-String Dynamics in production for K mesons
O. Kot, T. Obikhod, O. Okhrimenko +1
Heavy ion collisions provide a unique probe of the quark-gluon plasma properties. The role of partonic degrees of freedom in p-Pb collisions at = 5 TeV by studying…
Computer modeling of production cross sections for beyond SM particles
Tetiana Obikhod, Ievgenii Petrenko
In the paper is presented computer modelling of BSM physics, such as Dark matter candidates, di-jet resonances and new Higgs bosons with the help of MCFM program.
RR charge calculation for D brane in B field
Tetiana Obikhod, Ievgenii Petrenko
The paper is connected with searches for the Ramond-Ramond charge of D branes in the presence of B field. The consideration of B field inclusion is an important physical and mathem…
Mass reconstruction of MSSM Higgs boson
T. V. Obikhod, I. A. Petrenko
The problems of Standard Model as well as questions related to Higgs boson properties led to the need for modeling of ttH associated production and Higgs boson decay to top quark p…
K-group identification of supergravity solutions
T. V. Obikhod, I. A. Petrenko
The problem with Bekenstein-Hawking entropy of black hole can be resolved with quantum gravity theory with Dp-branes as supergravity solutions of type IIB string theory. Dp-brane s…
B-tagging and searches for new physics beyond the Standard Model
T. V. Obikhod, I. A. Petrenko
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 t…
Computer modeling of properties of Kaluza-Klein particles and their searches at the LHC
T. V. Obikhod, I. A. Petrenko
The Standard Model problems lead to the new theories of extra dimensions: Randall-Sundrum model, Arkani-Hamed-Dimopoulos-Dvali model and TeV model. In the framework of these…
