Plasma-embedded positronium atom with energy-dependent potential
(2021)In this study, for the first time, the positronium atom embedded in the plasma environment with energy-dependent potential interaction, under spherical confinement is investigated. The more general exponential cosine ... -
Predicting -decay energy with machine learning
(2023/3/15)Q β represents one of the most important factors characterizing unstable nuclei, as it can lead to a better understanding of nuclei behavior and the origin of heavy atoms. Recently, machine learning methods have been shown ... -
Probe of axion-like particles in vector boson scattering at a muon collider
(05.09.2023)We have examined the sensitivity of the axion-like particles (ALP) couplings to electroweak gauge bosons in the diphoton production at a future muon collider. The collisions at the μ+μ− energies of 3 TeV, 14 TeV, and 100 ... -

Search for invisible dark photon in scattering at future lepton colliders
(Springer, 06.07.2022)For the first time, the production of a massive dark photon (DP) in the γe− scattering at the future lepton colliders ILC, CLIC, and CEPC is examined. The invisible decay mode of the DP is addressed. We have studied both ... -
Search for noncommutative interactions in γγ→γγ process at the LHC
(Springer, 28.09.2022)The noncommutative QED (NCQED) has a non-Abelian nature due to the presence of 3- and 4-photon vertices in the lagrangian. Thus, NCQED predicts a new physics contribution to the γγ→γγ scattering already at the tree level. ... -
