The X(3872) and the 3941 MeV peak in omega+J/Psi

Abstract

Belle data for the pi-pi mass spectrum in X(3872) -> pi-pi + JPsi are well fitted by rho + J/Psi with JPC = 1++, but are poorly fitted by the pi-pi S-wave. Formulae for partial wave amplitudes are given for all likely JPC and decay modes of the 3941 MeV peak in omega + J/Psi. Angular correlations involving up to five angles may allow a spin-parity determination, even with quite low statistics. Special attention is given to the case where X(3872) is a cusp or quasi-bound state with the same quantum numbers as the 3941 MeV peak.
