Neutrinos are the only particles in the Standard Model (SM) of particle physics that have only
been observed with left handed chirality to date. If right handed (RH) neutrinos exist, they …

We review the production of the matter–antimatter asymmetry in the early Universe, that is
baryogenesis, in out-of-equilibrium conditions induced by decays of heavy particles or by …

A bstract Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a
minimal and testable explanation of the baryon asymmetry of the Universe. In this work we …

We review the current status of the leptogenesis scenario originally proposed by Akhmedov,
Rubakov and Smirnov (ARS). It takes place in the parametric regime where the right-handed …

A bstract The extension of the Standard Model by heavy right-handed neutrinos can
simultaneously explain the observed neutrino masses via the seesaw mechanism and the …

ULYSSES is a python package that calculates the baryon asymmetry produced from
leptogenesis in the context of a type-I seesaw mechanism. The code solves the semi …

We calculate the relaxation rate of a scalar field in a plasma of other scalars and fermions
with gauge interactions using thermal quantum field theory. It yields the rate of cosmic …

In many realizations of leptogenesis, heavy right-handed neutrinos play the main role in the
generation of an imbalance between matter and antimatter in the early Universe. Hence, it is …

We estimate the thermal masses and damping rates of active (m< eV) and sterile (M∼ GeV)
neutrinos with thermal momenta k∼ 3T at temperatures below the electroweak crossover (5 …

A bstract We calculate the production rate of singlet fermions from the decay of neutral or
charged scalar fields in a hot plasma. We find that there are considerable thermal …
