Radion Induced Spontaenous Baryogenesis
, 2007 We describe a possible scenario for the baryogenesis arising when matter is added on the branes of a Randall-Sundrum model with a radion stabilizing potential.

Single Field Baryogenesis [PDF]
Physical Review Letters, 2005 We propose a new variant of the Affleck-Dine baryogenesis mechanism in which a rolling scalar field couples directly to left- and right-handed neutrinos, generating a Dirac mass term through neutrino Yukawa interactions. In this setup, there are no explicitly CP violating couplings in the Lagrangian.

Electroweak baryogenesis driven by extra top Yukawa couplings
Physics Letters B, 2018 We study electroweak baryogenesis driven by the top quark in a general two Higgs doublet model with flavor-changing Yukawa couplings, keeping the Higgs potential CP invariant.

BARYOGENESIS BY QUANTUM GRAVITY [PDF]
Modern Physics Letters A, 2008 A novel mechanism of baryogenesis is proposed on the basis of the phase transition from the conformal invariant spacetime to the Einstein spacetime in quantum gravity. Strong-coupling gravitational excitations with dynamical mass about 1017 GeV are generated at the transition. They eventually decay into ordinary matters.

Spontaneous baryogenesis from asymmetric inflaton
Physics Letters B, 2016 We propose a variant scenario of spontaneous baryogenesis from asymmetric inflaton based on current–current interactions between the inflaton and matter fields with a non-zero B−L charge.

Baryogenesis and low energy CP violation [PDF]
, 1999 CP violation is a crucial component in the creation of the matter - anti matter asymmetry of the universe. An important open question is whether the CP violating phenomena observeable in terrestrial experiments have any relation with those responsible ...

Baryogenesis in Minkowski spacetime [PDF]
Based on a mechanism originally suggested for causal fermion systems, the present paper paves the way for a rigorous treatment of baryogenesis in the language of differential geometry and global analysis.

New Journal of Physics, 2012 Electroweak baryogenesis (EWBG) remains a theoretically attractive and experimentally testable scenario for explaining the cosmic baryon asymmetry. We review recent progress in computations of the baryon asymmetry within this framework and discuss their ...

On Baryogenesis from a Complex Inflaton
, 2021 We derive the particle asymmetry due to inflationary baryogenesis involving a complex inflaton, obtaining a different result to that in the literature.
