Cancellation mechanism for the electron electric dipole moment connected with the baryon asymmetry of the Universe [PDF]
Physical Review D, 2019 We elucidate a cancellation mechanism for the electric dipole moment of the electron in the general two Higgs doublet model. The impressive improvement by the ACME Collaboration in 2018 suggests the presence of a new electron Yukawa coupling that brings ...

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 A difference in electric potential in a static conductor inside a static magnetic field and an anisotropic and asymmetric distribution of neutrons emitted in nuclear reactions induced by ultrasound are assumed as marks of local Lorentz invariance (LLI) violation.

Two-component dark matter with cogenesis of the baryon asymmetry of the Universe [PDF]
Physical Review D, 2019 We discuss the possibility of realising a two-component dark matter (DM) scenario where the two DM candidates differ from each other by virtue of their production mechanism in the early universe.

Calculated Event Rates for Axion Detection via Atomic and Nuclear Processes
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 The possibility of detection of 5.5 MeV and 14.4 keV solar axions by observing axion‐induced nuclear and atomic transitions is investigated. The presence of nuclear transitions between spin orbit partners can be manifested by the subsequent deexcitation via gamma ray emissions.

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties. We obtain new experimental limits on the scale of compositeness, the mixing with singlets and doublets with the

Properties of the quark‐gluon plasma created in heavy‐ion collisions
Astronomische Nachrichten, Volume 342, Issue 5, Page 715-726, June 2021., 2021 Abstract We review the properties of the strongly interacting quark‐gluon plasma (QGP) at finite temperature and baryon chemical potential as created in heavy‐ion collisions at ultrarelativistic energies. The description of the strongly interacting (non‐perturbative) QGP in equilibrium is based on the effective propagators and couplings from the ...

An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The glueballs lead to gluon and QCD monopole condensations as by‐products of color confinement. A color dielectric function G(∣ϕ∣) coupled with a Abelian gauge field is properly defined to mediate the glueball interactions at confining regime after spontaneous symmetry breaking (SSB) of the gauge symmetry. The particles are expected to form through the

Common origin of baryon asymmetry, Dark Matter and neutrino mass [PDF]
Journal of High Energy Physics, 2018 A bstractIn this work, we explain three beyond standard model (BSM) phenomena, namely neutrino masses, the baryon asymmetry of the Universe and Dark Matter, within a single model and in each explanation the right handed (RH) neutrinos play the prime role.

Supersymmetry protects the primordial baryon asymmetry [PDF]
Physics Letters B, 1992 It has been argued that any primordial B+L asymmetry existing at very high temperatures can be subsequently erased by anomalous electroweak effects. We argue that this is not necessarily the case in the supersymmetric standard model because, apart from B and/or L, there are, above a certain temperature $T_{SS}$, two other anomalous U(1) currents.
