Testing F-theory GUTs with the Axiverse

Michael Nee, Mario Reig, Timo Weigand

We show that axions coupled to photons in F-theory Grand Unified Theories (GUTs) satisfy the coupling-to-mass relation $g_{aγ} / m_{a} \leq C \frac{α _{em}}{2 π} \frac{1}{m _{π} f _{π}}$ ,…

Heterotic String Theory Suggests a QCD Axion Near 0.5 neV

Joshua N. Benabou, Giulio Alvise Dainelli, Mario Reig +1

We show that in heterotic string theory -- and dual corners of the landscape including Type I string theory -- the QCD axion mass is bounded from below by $m_{a} ≳ 0.5$ neV, a…
