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 ...

Nuclear Physics B - Proceedings Supplements, 1994 A review on the present state of the baryogenesis is given with an emphasis on electroweak baryogenesis. Technical details of the numerous models considered in the literature are not elaborated but unresolved problems of the issue are considered. Different logically possible alternatives of the electroweak scenarios are presented.

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

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-

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 ...

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.

Baryogenesis from symmetry principle
Physics Letters B, 2016 In this work, a formalism based on symmetry which allows one to express asymmetries of all the particles in terms of conserved charges is developed. The manifestation of symmetry allows one to easily determine the viability of a baryogenesis scenario and

Axionic electroweak baryogenesis [PDF]
Physics Letters B, 2019 An axion can make the electroweak phase transition strongly first-order as required for electroweak baryogenesis even if it is weakly coupled to the Higgs sector.

Physics Letters B, 2018 We propose a model of baryogenesis achieved by the annihilation of non-thermally produced WIMPs from decay of heavy particles, which can result in low reheating temperature. Dark matter (DM) can be produced non-thermally during a reheating period created
