The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The recent CDF‐II measurement of the W‐boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low‐Scale Seesaw mechanisms, this tension can be resolved.

Deducing the EOS of dense neutron star matter with machine learning
Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023 Abstract The interior of a neutron star is a unique astrophysical laboratory for studying matter at extreme densities and pressures beyond what is replicable in terrestrial experiments. While there is no direct way to simulate the interior of these stars, one promising avenue to learning more about the equation of state (EOS) of such matter is through ...

Baryon asymmetry and dark matter [PDF]
Physics Letters B, 1998 We study the implications of a large baryogenesis temperature, $T_B = O(10^{10}$ GeV), on the mass spectrum of superparticles in supersymmetric extensions of the standard model. Models with a neutralino as lightest superparticle (LSP) are excluded. A consistent picture is obtained with the gravitino as LSP, followed by a higgsino-like neutralino (NSP).

Unconventional reconciliation path for quantum mechanics and general relativity
IET Quantum Communication, Volume 3, Issue 2, Page 99-111, June 2022., 2022 Abstract Physics in general is successfully governed by quantum mechanics at the microscale and principles of relativity at the macroscale. Any attempts to unify them using conventional methods have somewhat remained elusive for nearly a century up to the present stage. Here, a classical gedanken experiment of electron‐wave diffraction of a single slit

Expanding Nuclear Physics Horizons with the Gamma Factory
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 The Gamma Factory is an ambitious proposal for a source of photons with energies up to hundreds of MeV and photon fluxes exceeding those of the currently available gamma sources by orders of magnitude. The paper surveys the new opportunities in nuclear physics and related fields that may be afforded by the this facility. Abstract The Gamma Factory (GF)

Kaon oscillations and baryon asymmetry of the Universe [PDF]
Physical Review D, 2019 Baryon asymmetry of the universe (BAU) is naturally explained with $K^0-K^{0'}$ oscillations of a newly developed mirror-matter model and new understanding of quantum chromodynamics (QCD) phase transitions. A consistent picture for the origin of both BAU

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We review the two‐ and three‐body baryonic B decays with the dibaryon (BB′¯) as the final states. Accordingly, we summarize the experimental data of the branching fractions, angular asymmetries, and CP asymmetries. Using the W‐boson annihilation (exchange) mechanism, the branching fractions of B⟶BB′¯ are shown to be interpretable.

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we have investigated the density perturbations and cosmological evolution in the FLRW universe in the presence of a cosmic magnetic field, which may be assumed to mimic primordial magnetic fields. Such magnetic fields have sufficient strength to influence galaxy formation and cluster dynamics, thereby leaving an imprint on the CMB ...
