PROBING SCALAR MESON STRUCTURES IN χc1 DECAYS INTO PSEUDOSCALAR AND SCALAR

Abstract

We evaluate the decay branching ratios of χc1 → PS, in a quark model parametrization scheme, where P and S stand for pseudoscalar and scalar meson, respectively. An interesting feature of this decay process is that the [Formula: see text] annihilate via the pQCD hair-pin diagram is supposed to be dominant. Hence, this decay process should be sensitive to the quark components of the final-state light mesons, and would provide a great opportunity for testing the mixing relations among the scalar mesons, i.e. f0(1370), f0(1500) and f0(1710), by tagging the final state pseudoscalar mesons.
