Abstract

Description

We describe how difficult it is to realise baryogenesis in models where the fundamental scale in nature is as low as TeV. The problem becomes even more challenging if we assume that there are only {\it two} extra compact spatial dimensions, because thermal history of such a Universe is strongly constrained by various cosmological and astrophysical bounds which translate the maximal temperature of the Universe which must not exceed $\sim {\cal O}(10)$MeV. This simply reiterates that the observed baryon asymmetry must be synthesised just above the nucleosynthesis scale. In this talk we address how to construct a simple model which can overcome this challenge.
