The Width of a Beta-decay-induced Antineutrino Wavepacket

B. J. P. Jones, E. Marzec, J. Spitz

The time evolution of a neutrino is dependent on its initial properties at creation including flavor, energy, and wavepacket size. There exists no solid theoretical prediction for…

Freezing-in hadrophilic dark matter at low reheating temperatures

Prudhvi N. Bhattiprolu, Gilly Elor, Robert McGehee +1

If the reheating temperature at the end of inflation is low, of order 10 MeV, then dark matter produced through ultraviolet freeze-in has a large direct detection cross section. We…
