Chirality in cosmology

Marc Kamionkowski
Johns Hopkins


I have long been interested in the possibility to seek signatures of new symmetry-breaking physics in cosmology. In this talk, I will discuss recent work along these, and related, lines. I will discuss some new signatures of chirality in the cosmic microwave background, in the gravitational-wave background, and with 21-cm signals from the dark ages. It will be a fairly technical talk, but hopefully some interesting new things will emerge.
