Cosmological particle production and pairwise hotspots on the CMB
Abstract Heavy particles with masses much bigger than the inflationary Hubble scale H *, can get non-adiabatically pair produced during inflation through their couplings to the inflaton. If such couplings give rise to time-dependent masses for the heavy particles, then following their production, th...
