Relativistic treatments of quantum plasma-immersed Li, Na, K atoms
(2022)A relativistic investigation for Li, Na and K atoms immersed in a quantum plasma environment, under the influence of spherical encompassment and external electric field is carried out in this study, for the first time. ... -
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. ... -
