Two-photon and one-photon-one-vector meson decay widths of the f0(1370), f2(1270), f0(1710), f2'(1525), and K2*(1430)

We calculate the radiative decay widths, two-photon (γγ) and one-photon-one-vector meson (Vγ), of the dynamically generated resonances from vector-meson-vector-meson interaction in a unitary approach based on the hidden-gauge Lagrangians. In the present paper we consider the following dynamically generated resonances: f0(1370), f0(1710), f2(1270), f2'(1525), K2*(1430), two strangeness=0 and isospin=1 states, and two strangeness=1 and isospin=1/2 states. For the f0(1370) and f2(1270) we reproduce the previous results for the two-photon decay widths and further calculate their one-photon-one-vector decay widths. For the f0(1710) and f2'(1525) the calculated two-photon decay widths are found to be consistent with data. The ρ0γ, ωγ and φγ decay widths of the f0(1370), f2(1270), f0(1710), f2'(1525) are compared with the results predicted by other approaches. The K*+γ and K*0γ decay rates of the K2*(1430) are also calculated and compared with the results obtained in the framework of the covariant oscillator quark model. The results for the two states with strangeness=0, isospin=1 and two states with strangeness=1, isospin=1/2 are predictions that need to be tested by future experiments.
