Global symmetries: locality, unitarity, and regularity
Ibrahima Bah, Shlomo S. Razamat, Michal Shemesh +1
We study the apparent tension between locality and unitarity for symmetries in quantum field theory. This emerges in the context of categorical symmetries where symmetry operators…
Lectures on Generalized Symmetries
Lakshya Bhardwaj, Lea E. Bottini, Ludovic Fraser-Taliente +4
These are a set of lecture notes on generalized global symmetries in quantum field theory. The focus is on invertible symmetries with a few comments regarding non-invertible symmet…
Axiverse Strings
John March-Russell, Hannah Tillim
If the QCD axion solves the strong CP problem then light axion-like-particles (ALPs) are expected to be ubiquitous in string theory - the string axiverse. Such ALPs can be the QCD…
Gravitational Production of a Conformal Dark Sector
Michele Redi, Andrea Tesi, Hannah Tillim
Dark sectors with purely gravitational couplings to the Standard Model are unavoidably populated from the SM plasma by graviton exchange, and naturally provide DM candidates. We ex…
Reproductive Freeze-In of Self-Interacting Dark Matter
John March-Russell, Hannah Tillim, Stephen M. West
We present a mechanism for dark matter (DM) production involving a self-interacting sector that at early times is ultra-relativistic but far-underpopulated relative to thermal equi…
Black Hole Genesis of Dark Matter
Olivier Lennon, John March-Russell, Rudin Petrossian-Byrne +1
We present a purely gravitational infra-red-calculable production mechanism for dark matter (DM). The source of both the DM relic abundance and the hot Standard Model (SM) plasma i…
