摘要

We demonstrate the possibility of a good description of the processes phi(1020) -> gamma pi pi and phi(1020) -> gamma f(0)(980) within the framework of the nonrelativistic quark model assuming f(0)(980) to be a dominantly quark-antiquark system. Different mechanisms of the radiative decay, that is, the emission of a photon by the constituent quark (additive quark model) and charge-exchange current, are considered. We also discuss the status of the threshold theorem applied to the studied reactions, namely, the behavior of the decay amplitude at M-pi pi -> m(phi) and mf(0) -> m(phi). In conclusion, the arguments favoring the q (q) over bar origin of f(0)(980) are listed. (c) 2005 Pleiades Publishing, Inc.
