Interpreting 750 GeV diphoton excess in plain NMSSM
NMSSM has enough ingredients to explain the diphoton excess at 750 GeV: singlet-like
(pseudo) scalar (a) s and higgsinos as heavy vector-like fermions. We consider the
production of the 750 GeV singlet-like pseudo scalar a from a decay of the doublet-like
pseudo scalar 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 at 750 GeV.

Abstract
NMSSM has enough ingredients to explain the diphoton excess at 750 GeV: singlet-like (pseudo) scalar (a) s and higgsinos as heavy vector-like fermions. We consider the production of the 750 GeV singlet-like pseudo scalar a from a decay of the doublet-like pseudo scalar 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 at 750 GeV.
