Trans-Planckian wimpzillas
Trans-Planckian wimpzillas
Two previously proposed conjectures—gravitational trans-Planckian particle creation in the expanding universe, and the existence of ultraheavy stable particles with masses up to the Planck scale (wimpzillas)—are combined in a proposal for trans-Planckian particle creation of wimpzillas. This new scenario leads to a huge enhancement in their production compared to mechanisms …
