On 750 GeV Diphoton Resonance in Stringy Standard-Like Models
  The LHC diphoton excess 750 GeV is discussed in a string-inspired standard-like model. Precisely, a singlet scalar-extended SM from a vacua of four stacks of intersecting D6-branes giving rise to a large gauge symmetry is considered. Besides its relevant couplings to the SM sector, the involved scales allow for a scalar mass near to the reported diphoton excess.
