Dark Medium Modified Dispersion Relations

arXiv:1110.1853

Abstract

We suggest that the dark side of the universe builds a dark medium modifying the Standard Model particle dispersion relations. We introduce the generic form for the modified dispersion relations and provide explicit models of the dark medium. We use the derived neutrino dispersion relations to show that the size of the corrections are smaller than the SN1987a bounds. We argue that before invoking modifications of Einstein's theory of relativity one should investigate the dark medium effects.

Revised version focusing only on the dark matter induced modified standard model dispersion relations and comparison with current data
