bstract
Low scale string models naturally have axion-like pseudoscalars which couple directly to gluons and photons (but not
W
’s) at tree level. We show how they typically get tree level masses in the presence of closed string fluxes , consistent with the axion discrete gauge symmetry, in a way akin of the axion monodromy of string inflation and relaxion models. We discuss the possibility that the hints for a resonance at 750 GeV recently reported at ATLAS and CMS could correspond to such a heavy axion state (
megaxion
). Adjusting the production rate and branching ratios suggest the string scale to be of order
M
s
≃ 7-10
4
TeV, depending on the compactification geometry. If this interpretation was correct, one extra
Z
’ gauge boson could be produced before reaching the string threshold at LHC and future colliders. |
