Nambu-Goldstone Affleck-Dine baryogenesis

Journal of High Energy Physics, 2019
The Affleck-Dine mechanism creates the baryon asymmetry of the universe from an angular motion of a complex scalar field. The mechanism is efficient and allows for a low reheating temperature of the universe if the scalar field has a flat potential along

Scalar–tensor baryogenesis: a scalar–tensor completion of gravitational baryogenesis

Physics Letters B
We propose Scalar–Tensor Baryogenesis (STB), in which the CP-violating bias needed for baryogenesis is sourced by the gravitational scalars that appear in scalar–tensor representations of modified gravity.

Excited lepton baryogenesis

EPJ Web of Conferences, 2017
The excited leptons that share the quantum numbers with the Standard Model leptons but have larger masses are widespread in many promising new physics theories.

Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields

Journal of High Energy Physics, 2017
We perform numerical simulations of Cold Electroweak Baryogenesis, including for the first time in the Bosonic sector the full electroweak gauge group SU(2) × U(1) and CP-violation.

Gravitational baryogenesis in f(T, Lm) gravity

Nuclear Physics B
The observed matter–antimatter asymmetry of the Universe remains a fundamental challenge in modern physics. In this work, we explore gravitational baryogenesis within the framework of f(T, Lm) gravity, where the gravitational Lagrangian depends on both ...
