Description

We propose a simple mechanism for generating ordinary luminous and dark matter during cosmic inflation. This scenario involves an extension of the Standard Model through the introduction of a dark matter candidate/s and an anomalous U(1)_X gauge group. The general framework developed is found to be able to replicate both the observed matter-antimatter asymmetry and the dark-to-visible matter mass density. (Based on arxiv: 1503.02366)
