A bstract Axion-like particles can source the baryon asymmetry of our Universe through
spontaneous baryogenesis. Here we clarify that this is a generic outcome for essentially any …

A derivative coupling of an axionlike particle (ALP) with a BL current may lead to the baryon
asymmetry of the Universe via spontaneous leptogenesis provided a lepton number …

We show that both the baryon asymmetry of the universe and dark matter (DM) can be
accounted for by the dynamics of a single axionlike field. In this scenario, the observed …

We present a new scenario for generating the baryon asymmetry of the Universe that is
induced by a Nambu-Goldstone (NG) boson. The shift symmetry naturally controls the …

Recently the ATLAS and CMS Collaborations have reported evidence of a diphoton excess
which may be interpreted as a pseudoscalar boson S with a mass around 750 GeV. To …

We propose a new class of spontaneous baryogenesis models that does not produce
baryon isocurvature perturbations. The baryon chemical potential in these models is …

The recent measurement of the Higgs boson mass implies a relatively slow rise of the
Standard Model Higgs potential at large scales, and a possible second minimum at even …
