Once more about the K K molecule approach to the light scalars
N. N. Achasov, A. V. Kiselev
Abstract
We show that the recent paper kalash, claiming that the radiative decays ϕ a0(980)γand ϕ f0(980)γshould be of the same order of magnitude regardless of whether the a0(980) and f0(980) are compact four-quark states or extended K K molecule states, is misleading.
