Some Aspects of String Cosmology and the LHC.

I discuss some (unconventional) aspects of String Cosmology of relevance to supersymmetric dark matter searches at the Large Hadron Collider (LHC) at CERN. In particular, I analyse the rôle of time-dependent dilaton fields in relaxing some of the stringent constraints that characterise minimal supersymmetric models in standard cosmology. I also study briefly CPT-violating aspects of brane Universe models with spacetime brane defects at early epochs and their potential relevance to the observed Baryon Asymmetry. [ABSTRACT FROM AUTHOR]
