On gravitational baryogenesis in inflationary Cosmologies
Ian B. Whittingham
The present study investigates the feasibility of generating the observed baryon-antibaryon asymmetry of the Universe by gravitational baryogenesis during the inflationary phas…
Dark matter relic density in scalar-tensor gravity revisited
Michael T. Meehan, Ian B. Whittingham
We revisit the calculation of dark matter relic abundances in scalar-tensor gravity using a generic form for the coupling between the scalar field and…
Dark matter relic density in Gauss-Bonnet braneworld cosmology
Michael T. Meehan, Ian B. Whittingham
The relic density of symmetric and asymmetric dark matter in a Gauss-Bonnet (GB) modified Randall-Sundrum (RS) type II braneworld cosmology is investigated. The existing study of s…
Asymmetric dark matter in braneworld cosmology
Michael T. Meehan, Ian B. Whittingham
We investigate the effect of a braneworld expansion era on the relic density of asymmetric dark matter. We find that the enhanced expansion rate in the early universe predicted by…
