N2 - The diphoton excess around mS=750 GeV observed at ATLAS and CMS can be interpreted as coming from S=H and A, the neutral components of a second Higgs doublet. If so, then the consistency of the light Higgs decays with the Standard Model predictions provides upper bounds on the rates of Sto VV, hZ, hh decays. On the other hand, if h to tau mu decay is established, then a lower bound on the rate of S to tau mu decay arises. Requiring that Gamma_S less 45 GeV gives both an upper and a lower bound on the rotation angle from the Higgs basis (Phi_v,Phi_A) to the mass basis (Phi_h,Phi_H). The charged scalar, with mH± 750 GeV, is produced in association with a top quark, and can decay to μ±ν, τ±ν, tb and W±h.
