Big Bounce Genesis

Abstract

We report on the possibility to use dark matter particle's mass and its cross section as a smoking gun signal of the existence of a Big Bounce at the early stage in the evolution of our currently observed universe. A model independent study of dark matter production in the pre-bounce contraction and the post-bounce expansion epochs of the bounce universe reveals a new venue for achieving the observed relic abundance of our present universe, in which a significantly smaller amount of dark matter with a smaller cross section -- as compared to the prediction of Standard Cosmology -- is produced and carries the information about the bounce universe evolution. Once the values of dark matter mass and cross section are obtained by direct detection in laboratories, this alternative route becomes a signature of the bounce universe scenario.
