Quantum Entanglement Asymmetry and the Cosmic Matter–Antimatter Imbalance: A Theoretical and Observational Analysis [PDF]
EntropyWe propose a distinct mechanism to explain the matter–antimatter imbalance observed in the universe, rooted in quantum entanglement asymmetry (QEA). Our concept of QEA differs from its usage in the recent literature, where it typically measures how much ...

Journal of High Energy Physics, 2021 A novel mechanism, “catalyzed baryogenesis”, is proposed to explain the observed baryon asymmetry in our universe. In this mechanism, the motion of a ball-like catalyst provides the necessary out-of-equilibrium condition, its outer wall has CP-violating ...

Journal of High Energy Physics, 2022 We propose a new mechanism to simultaneously explain the observed dark matter abundance and the baryon asymmetry of the Universe. The mechanism is based on the Filtered Dark Matter scenario, where dark matter particles acquire a large mass during a first-

Physics Letters B, 2023 We study the possibility of electroweak baryogenesis in the standard model with a complex scalar field, focusing mainly on a degenerate scalar scenario.

Models of the Universe: Ontological and Physical Problems [PDF]
Философия и космология, 2022 The primary target of this paper is a philosophical analysis of modern models of the universe in cosmology. Understanding the existence of being is directly related to understanding both the world and oneself.

Introduction to Electroweak Baryogenesis
Galaxies, 2022 We present a pedagogical introduction to the electroweak baryogenesis. The review focuses principally on the sphaleron and baryon number (non)-conservation or chiral anomaly. All results are derived with details for a self-contained reading.

On Extra Top Yukawa Couplings of a Second Higgs Doublet
Universe, 2022 A very likely New Physics in plain sight, but that the community does not see, is a second Higgs doublet that has a second set of Yukawa couplings. The extra tt and tc couplings can each drive baryogenesis, with O(1) Higgs quartic couplings providing a ...

CP Violation for the Heavens and the Earth
Universe, 2022 Electroweak baryogenesis can be driven by the top quark in a general two Higgs doublet model with extra Yukawa couplings. Higgs quartics provide the first order phase transition, while extra top Yukawa coupling ρtt can fuel the cosmic baryon asymmetry ...

Constraining f(T,T) gravity with gravitational baryogenesis
Physics Letters B, 2023 Gravitational baryogenesis is one of the mechanisms which help us to explore more about our early universe, especially baryon-anti-baryon asymmetry.

A new bound on CP violation in the τ lepton Yukawa coupling and electroweak baryogenesis
Journal of High Energy Physics, 2021 The origin of the matter-antimatter asymmetry in the Universe is a fundamental question of physics. Electroweak baryogenesis is a compelling scenario for explaining it but it requires beyond the Standard Model sources of the CP symmetry violation.
