Once more about the K\bar K molecule approach to the light scalars

Abstract

We show that the recent paper \cite{kalash}, claiming that the radiative decays ϕ\to a_0(980)γand ϕ\to f_0(980)γshould be of the same order of magnitude regardless of whether the a_0(980) and f_0(980) are compact four-quark states or extended K\bar K molecule states, is misleading.
