Descripción
NMSSM has enough ingredients to explain the diphoton excess at 750 GeV. We consider the production of the 750 GeV singlet-dominated pseudoscalar $a$ from a decay of the doublet-dominated pseudoscalar $A$, and the subsequent decay of $a$ into two photons via higgsino loop. We demonstrate that this cascade decay of the NMSSM Higgs bosons can explain the diphoton excess in the 13 TeV data consistently with the absence of a significant excess in the 8 TeV data.
