χc1 decays into a pseudoscalar meson and a vector-vector molecule

We evaluate ratios of the χc1 decay rates to η (η′, K−) and one of the f0(1370), f0(1710), f2(1270), f2′(1525), K2*(1430) resonances, which in the local hidden gauge approach are dynamically generated from the vector-vector interaction. With the simple assumption that the χc1 is a singlet of SU(3),...

Description
Summary:We evaluate ratios of the χc1 decay rates to η (η′, K−) and one of the f0(1370), f0(1710), f2(1270), f2′(1525), K2*(1430) resonances, which in the local hidden gauge approach are dynamically generated from the vector-vector interaction. With the simple assumption that the χc1 is a singlet of SU(3), and the input from the study of these resonances as vector-vector molecular states, we describe the experimental ratio B(χc1→ηf2(1270))/B(χc1→η′f2′(1525)) and make predictions for six more ratios that can be tested in future experiments.
