A Supernova Constraint on F-theory
Sebastian Vander Ploeg Fallon, James Halverson, Liam McAllister +1
We study constraints on the quantum chromodynamics (QCD) axion in F-theory, a strongly coupled limit of string theory. We build models of QCD from compactifications to four dimensi…

Glimmers from the Axiverse
Naomi Gendler, David J. E. Marsh, Liam McAllister +1
We study axion-photon couplings in compactifications of type IIB string theory. We find that these couplings are systematically suppressed compared to the inverse axion periodicity…
