| 英文摘要 | The decay widths of upsilon(ns) -> (d) over bar*(2380)+x with n=1,2,3 are studied in a phenomenological way. with the help of crossing symmetry, the decay widths are obtained by investigating the imaginary part of the forward scattering amplitudes between d* and upsilon(ns). the wave functions of d* and deuteron obtained in previous studies are used for calculating the amplitude. the interaction between d* (d) and upsilon is governed by the quark-meson interaction, where the coupling constant is determined by fitting the observed widths of upsilon(ns) -> (d) over bar*+x. the numerical results show that the decay widths of upsilon (ns) -> (d) over bar*+x are about 2-10 times smaller than that of (d) over bar*+x . the calculated momentum of (d) over bar* is in the range 0.3-0.8 gev. therefore, it is very likely that one can find (d) over bar* (2380) in these semi-inclusive decay processes. |
