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 …

Electroweak baryogenesis (EWBG) remains a theoretically attractive and experimentally
testable scenario for explaining the cosmic baryon asymmetry. We review recent progress in …

We review observational evidence for a matter–antimatter asymmetry in the early universe,
which leads to the remnant matter density we observe today. We also discuss bounds on the …

We show that, leaving aside accelerated cosmic expansion, all experimental data in high
energy physics that are commonly agreed to require physics beyond the Standard Model …

Right-handed neutrinos offer an elegant solution to two well-established phenomena
beyond the Standard Model (SM)—masses and oscillations of neutrinos, as well as the …

It is widely believed that electroweak baryogenesis should be suppressed in strong phase
transitions with fast-moving bubble walls, but this effect has never been quantitatively …

We present a formulation of the quantum kinetic equations (QKEs), which govern the
evolution of neutrino flavor at high density and temperature. Here, the structure of the QKEs …

A bstract Motivated by 3.9σ evidence of a CP-violating phase beyond the standard model in
the like-sign dimuon asymmetry reported by D∅, we examine the potential for two Higgs …

In this Letter we demonstrate that what was previously considered as different mechanisms
of baryon asymmetry generation involving two right-handed Majorana neutrinos with …

Vanilla leptogenesis within the type I seesaw framework requires the mass scale of the right-
handed neutrinos to be above 1 0 9 GeV. This lower bound can be avoided if at least two of …
