Аннотация:Recently reported diphoton excesses at LHC is interpreted to be connected with heavy WW zero spin resonances. The resonances appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by couplng constant $\lambda$. The $\gamma \gamma$ 750 GeV anomaly is considered to correspond to weak isotopic spin 0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agraa with ATLAS data. Effects are predicted in a production of $W^+W^-,(Z<\gamma)(Z,\gamma)$ via resonance $X_{PS}$ with $M_{PS}\simeq750 GeV$, which could be reliably checked at the upgraded LHC at $\sqrt{s}=13 TeV$. The coupling constant of the triple anomalous interaction is estimated to be $\lambda = -0.01\pm 0.005$ in an agreement with existing restrictions. Specific predictions of the hypothesis are significant effects in decay channels $X_{PS} \to \gamma l^+ l^-, X_{PS} \to l^+l^_l^+l^-
(l=e,\mu)$.
