Unraveling the Dirac Neutrino with Cosmological and Terrestrial Detectors
Peter Adshead, Yanou Cui, Andrew J. Long +1
We point out a correlation between the effective number of relativistic degrees of species , the cosmologically measured , and the…
Completely Dark Photons from Gravitational Particle Production During Inflation
Edward W. Kolb, Andrew J. Long
Starting with the de Broglie--Proca Lagrangian for a massive vector field, we calculate the number density of particles resulting from gravitational particle production (GPP) durin…
Towards an all-orders calculation of the electroweak bubble wall velocity
Stefan Hoeche, Jonathan Kozaczuk, Andrew J. Long +2
We analyze Higgs condensate bubble expansion during a first-order electroweak phase transition in the early Universe. The interaction of particles with the bubble wall can be accom…
Tests of Dark MACHOs: Lensing, Accretion, and Glow
Yang Bai, Andrew J. Long, Sida Lu
Dark matter could take the form of dark massive compact halo objects (dMACHOs); i.e., composite objects that are made up of dark-sector elementary particles, that could have a macr…
