We investigate the minimal supergravity signals at the Large Hadron
Collider in the context of supercritical string cosmology (SSC). In this
theory, the presence of a time dependent dilaton provides us with a
smoothly evolving dark energy and modifies the dark matter allowed
region of the minimal supergravity model with standard cosmology. Such a
dilaton dilutes the supersymmetric dark matter density (of neutralinos)
by a factor O(10) and consequently the regions with too much dark matter
in the standard scenario are allowed in the SSC. The final states
expected at the Large Hadron Collider in this scenario, unlike the
standard scenario, consist of Z bosons, Higgs bosons, and/or high energy
taus. We show how to characterize these final states and determine the
model parameters. Using these parameters, we determine the dark matter
content and the neutralino-proton cross section. All these techniques
can also be applied to determine model parameters in SSC models with
different supersymmetry breaking scenarios
