Description
We discuss the origin of exotic statistics, in the sense of Tsallis, in the context of certain models of string cosmology, in which the dilaton expectation value, and hence the string coupling, are "fuzzy".Situations like this can characterize some versions of string spacetime foam. The effect of such stochastically fluctuating spacetimes on particle statistics is examined, determining the conditions under which exotic statistics for dark matter particles is achieved. Following then standard treatments we derive the modified Boltzmann equation for thermal relics and discuss the effects of this exotic statistics on the relic abundances.
