Update on 750 GeV diphotons from closed string states

Motivated by the recent update on LHC searches for narrow and broad resonances decaying into diphotons we reconsider the possibility that the observed peak in the invariant mass spectrum at Mγγ=750 GeV originates from a closed string (possibly axionic) excitation φ (associated with low mass scale st...
