| 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. |
