Abstract. Recently reported diphoton excesse 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 coupling constant λ. The γγ 750 GeV anomaly is considered to correspond to weak isotopic spin 0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in a production of W + W − , (Z, γ)(Z, γ) via resonance X PS with M PS 750 GeV, which could be reliably checked at the upgraded LHC at √ s = 13 T eV. In coupling constant of the triple anomalous interaction is estimated to be λ = − 0.010 ± 0.005 in an agreement with existing restrictions. Specific predictions of the hypothesis are significant effects in decay channels X PS → γ l + l

diboson and diphoton excesses at LHC are interpreted to be connected with heavy W W zero spin resonances. The resonances appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant λ. The 2 T eV anomaly tentatively corresponds to weak isotopic spin 2 scalar state and the γγ 750 GeV anomaly corresponds to weak isotopic spin 0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in a production of W + W − , (Z, γ)(Z, γ) via resonance X P S with M P S ≃ 750 GeV , which could be reliably checked at the upgraded LHC at √ s = 13 T eV . In the framework of an approach to the spontaneous generation of the triple anomalous interaction its coupling constant is estimated to be λ = − 0.02 ± 0.005 in an agreement with existing restrictions. Specific predictions of the hypothesis are significant effects in decay channels X P S → γ l + l − , X P S → l + l − l + l − (l = e, µ).Keywords: anomalous triple boson interaction; W-ball; spontaneous generation of an effective interaction.
