Higgs relaxation and the matter-antimatter asymmetry of the universe
Alexander Kusenko
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 larger sc…
Diluted equilibrium sterile neutrino dark matter
Amol V. Patwardhan, George M. Fuller, Chad T. Kishimoto +1
We present a model where sterile neutrinos with rest masses in the range ~ keV to ~ MeV can be the dark matter and be consistent with all laboratory, cosmological, large-scale stru…
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…
Signals from dark atom formation in halos
Lauren Pearce, Kalliopi Petraki, Alexander Kusenko
We consider indirect detection signals of atomic dark matter, with a massive dark photon which mixes kinetically with hypercharge. In significant regions of parameter space, dark m…
