Leptogenesis from spontaneous symmetry breaking during inflation
Yi-Peng Wu, Louis Yang, Alexander Kusenko
Symmetry breaking in the Higgs field via a non-minimal coupling to gravity or higher-dimensional interactions with the inflaton can lead to condensation at a large vacuum expectati…
Relaxation leptogenesis, isocurvature perturbations, and the cosmic infrared background
Masahiro Kawasaki, Alexander Kusenko, Lauren Pearce +1
Observations of cosmic infrared background (CIB) radiation exhibit significant fluctuations on small angular scales. A number of explanations have been put forth, but there is curr…
Leptogenesis via the 750 GeV pseudoscalar
Alexander Kusenko, Lauren Pearce, Louis Yang
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 explain the…
Baryogenesis via Elementary Goldstone Higgs Relaxation
Helene Gertov, Lauren Pearce, Francesco Sannino +1
We extend the relaxation mechanism to the Elementary Goldstone Higgs framework. Besides studying the allowed parameter space of the theory we add the minimal ingredients needed for…
Leptogenesis via Higgs Condensate Relaxation
Louis Yang, Lauren Pearce, Alexander Kusenko
An epoch of Higgs relaxation may occur in the early universe during or immediately following postinflationary reheating. It has recently been pointed out that leptogenesis may occu…
Leptogenesis Via Neutrino Production During Higgs Condensate Relaxation
Lauren Pearce, Louis Yang, Alexander Kusenko +1
During inflation, scalar fields, including the Higgs boson, may acquire a nonzero vacuum expectation value, which must later relax to the equilibrium value during reheating. In the…
