Decay Modes

In this proceeding, I report the most recent experimental results from BESIII about the XYZ sates. Two new X(3872) decay modes are observed, which is X(3872) → ωJ/ψ and X(3872) → π0χc1(1P). Precise measurement of cross sections of various channels reveal more fine structure about Y states. To study the property of Zc states, the Jp of Zc(3900) is determined with partial wave analysis, and a hint of new decay mode of Zc±(3900) → ρ±ηc are observed.

A partial wave analysis of the differential cross sections for the 180(p,OCO)15N reaction has been carried out by applying the formalism of .Blatt and Biedenharn (1952), made specific for this reaction. The differential cross sections, measured at 200 keV intervals from 6�6 to 10�4 MeV bombarding energy, were subjected to least-squares fitting to this specific analytic expression. Two resonances were given by the analysis, the 19p states being at 14�71 �0�07 MeV (1/2-) and 14�80�0�07 MeV (1/2 +).
