Spontaneous baryogenesis without baryon isocurvature [PDF]
, 2017 We propose a new class of spontaneous baryogenesis models that does not produce baryon isocurvature perturbations. The baryon chemical potential in these models is independent of the field value of the baryon-generating scalar, hence the scalar field ...

Numerical Tools for Electroweak Phase Transition
UniverseThe electroweak phase transition serves as a crucial portal to explore physics beyond the Standard Model, with profound implications for gravitational waves, baryogenesis, dark matter, and vacuum stability.

Electroweak phase transition and baryogenesis in composite Higgs models
Journal of High Energy Physics, 2018 We present a comprehensive study of the electroweak phase transition in composite Higgs models, where the Higgs arises from a new, strongly-coupled sector which confines near the TeV scale. This work extends our study in ref. [1].

Baryogenesis by brane collision [PDF]
Physical Review D, 2002 We present a new scenario for baryogenesis in the context of heterotic brane-world models. The baryon asymmetry of the universe is generated at a small-instanton phase transition which is initiated by a moving brane colliding with the observable boundary.

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.

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 The future long baseline experiments such as DUNE and T2HKK have promising prospects to determine the neutrino mass hierarchy and measuring standard CP phase δ. However, presence of possible nonstandard interactions of neutrinos with matter may intricate this picture and is the subject matter of the present work.

Role of cosmological gravitational particle production in baryogenesis [PDF]
We investigate the generation of the baryon asymmetry within the framework of cosmological gravitational particle production, employing the Bogoliubov approach.
