Gravitational particle creation for dark matter and reheating

27 Feb 2019 Hashiba Soichiro Yokoyama Jun'ichi

The purely gravitational dark matter (PGDM) which interacts with the standard model particles only by gravitational interaction has recently been discussed. Due to its feeble interaction, PGDM may be produced mainly by the gravitational particle creation, which plays an important role in the reheating after kinetically driven inflation and some potential-driven inflation without subsequent inflaton oscillating phase...
