abstract
We show that Supercritical-String-Cosmology (SSC) off-equilibrium and time-dependent-dilaton effects lead to a smoothly evolving dark energy for the last 10 billion years in concordance with all presently available astrophysical data. Such effects dilute by a factor O (10) the supersymmetric dark matter density (neutralinos), relaxing severe WMAP 1,3 constraints on the SUSY parameter space. Thus, LHC anticipated searches/discoveries may discriminate between conventional and Supercritical-String Cosmology.

Gravitino Freeze-In Dark Matter with an Additional Scalar Field
An additional scalar field dilutes gravitino freeze-in dark matter for matter-like equations of state, permitting larger reheating temperatures consistent with leptogenesis.
