Trans-Planckian wimpzillas
E. W. Kolb, A. A. Starobinsky, I. I. Tkachev
Two previously proposed conjectures--gravitational trans-Planckian particle creation in the expanding universe, and the existence of ultra-heavy stable particles with masses up to…
Extra dimensions present a new flatness problem
Daniel J. H. Chung, Edward W. Kolb, Antonio Riotto
There is no known fundamental reason to demand as a cosmological initial condition that the bulk possess an SO(3,1) isometry. On the contrary, one expects bulk curvature terms that…
WIMPZILLAS!
Edward W. Kolb, Daniel J. H. Chung, Antonio Riotto
There are many reasons to believe the present mass density of the universe is dominated by a weakly interacting massive particle (WIMP), a fossil relic of the early universe. Theor…
GUT baryogenesis after preheating: numerical study of the production and decay of X-bosons
E. W. Kolb, A. Riotto, I. I. Tkachev
We perform a fully non-linear calculation of the production of supermassive Grand Unified Theory (GUT) bosons during preheating, taking into account the fact that they are unst…
