Description
In this talk, I explore the early cosmology and the possibilities for dark matter candidates in Twin Higgs theories of the weak scale -- in particular, within a minimal implementation, the Fraternal Twin Higgs. The phenomenology of this class of models is rich: some highlights include the presence of a “twin WIMP miracle”; asymmetric twin dark matter made of twin baryons with the correct mass (set by dynamics underlying naturalness, not tuning) to explain the observed O(1) ratio of dark matter to baryon energy densities; and various new phase transitions beyond those of the Standard Model alone.
