A Phenomenological Analysis of Higher Fock State Contributions to the χcJ Decays
Tao Huang, Huifang Wu
Abstract
We present a phenomenological analysis of higher Fack state contributions to the χcJ decays by using the recent BES experimental data. It is found that the higher Fock state (cc)8g> makes an important contributions to the inclusive and exclusive processes with respect to that from the valence Fock state cc > of the χcJ and some constraints of these contributions are obtained for the χc0 and χc2 states in order to fit the experimental data.
