Once more about gauge invariance in ϕ\toγ\pi0\pi0

arXiv:hep-ph/0606003 · doi:10.1134/S1063778807050080

Abstract

It is argued that the realization of gauge invariance condition as a consequent of cancellation between the ϕ\toγf0\toγ\pi0\pi0 resonance contribution and a ϕ\toγ\pi0\pi0 background one, suggested in Ref. [1], is misleading.
