Baryon asymmetry and minimum length [PDF]
The Sixteenth Marcel Grossmann Meeting, 2021 So far there are two successful theories which describe the world around us. Quantum theory, which describes interactions on the smallest scales on one hand and General Relativity, which describes gravitational interactions on large scales on the other ...

Higgs troika for baryon asymmetry [PDF]
Physical Review D, 2019 To explain the baryon asymmetry of the Universe, we extend the Standard Model (SM) with two additional Higgs doublets with small vacuum expectation values. The additional Higgs fields interact with SM fermions through complex Yukawa couplings, leading to

Baryon asymmetry from the generalized uncertainty principle [PDF]
Physics Letters B, 2021 The unexplained observed baryon asymmetry in the Universe is a long-standing problem in physics, with no satisfactory resolution so far. To explain this asymmetry, three Sakharov conditions must be met.

PBH Evaporation, Baryon Asymmetry, and Dark Matter [PDF]
Journal of Experimental and Theoretical Physics, 2020 Sufficiently light primordial black holes (PBH) could evaporate in the very early universe and dilute the preexisting baryon asymmetry and/or the frozen density of stable relics.

Baryon asymmetry, dark matter and local baryon number [PDF]
Physics Letters B, 2013 We propose a new mechanism to understand the relation between baryon and dark matter asymmetries in the universe in theories where the baryon number is a local symmetry.

Baryon Asymmetry from a Composite Higgs Boson. [PDF]
Physical Review Letters, 2018 We study the nature of the electroweak phase transition (EWPT) in models where the Higgs boson emerges as a pseudo-Nambu-Goldstone boson of an approximate global symmetry of a new strongly interacting sector confining around the TeV scale.

Leptogenesis and gravity: Baryon asymmetry without decays [PDF]
Physics Letters B, 2016 A popular class of theories attributes the matter-antimatter asymmetry of the Universe to CP-violating decays of super-heavy BSM particles in the Early Universe.

Gravitational waves, bubble profile, and baryon asymmetry in the complex 2HDM [PDF]
Physical Review D, 2023 This study explores the generation of the observed baryon asymmetry of the Universe within the complex Two Higgs Doublet Model (C2HDM) while considering theoretical and current experimental constraints.

A Chern-Simons model for baryon asymmetry [PDF]
Nuclear Physics B, 2023 In search of a phenomenological model that would describe physics from Big Bang to the Standard Model (SM), we propose a model with the following properties (i) above an energy about Lambda_{cr}>10^{16} GeV there are Wess-Zumino supersymmetric preons and

Baryon asymmetry from Barrow entropy: theoretical predictions and observational constraints [PDF]
The European Physical Journal C, 2022 We investigate the generation of baryon asymmetry from the corrections brought about in the Friedman equations due to Barrow entropy. In particular, by applying the gravity-thermodynamics conjecture one obtains extra terms in the Friedmann equations that
