The 750 GeV diphoton excess reported by ATLAS and CMS indicates the presence of several pairs of the vectorlike matter multiplets around TeV scale. If that is the case, radiative corrections from the SU(3) gauge interaction significantly change from those of the minimal supersymmetric standard model, and the infrared-free nature of the gauge interaction leads to characteristic supersymmetry mass spectra: a ratio of a squark mass to the gluino mass, and scalar trilinear couplings are enhanced at the low-energy scale. Consequently, even in gaugino mediation models, the Higgs boson mass of 125 GeV is explained with the fairly light gluino of 2-3 TeV, which can be accessible at the LHC.
