Analytic Bounds on the Spectrum of Crossing Symmetric S-Matrices
Justin Berman
We derive two rigorous constraints on the spectrum of massive states in weakly coupled theories with massless scalars in the adjoint representation of a large- gauge group. Firs…

Freeze-in Leptogenesis via Dark-Matter Oscillations
Justin Berman, Brian Shuve, David Tucker-Smith
We study the cosmology and phenomenology of freeze-in baryogenesis via dark-matter oscillations, taking the dark matter to couple to Standard Model leptons. We investigate viable m…
