| 英文摘要 | Recently the BES Collaboration found evidence for the existence of the sigma meson in the process J/psi-->sigmaomega-->pipiomega at the BEPC. In this paper we first discuss the relevant coupling g(sigmapipi) and show that the linear sigma model gives rise to a reasonable description of the sigma decay into pi's; then we calculate the coupling constant g(J/psisigmaomega)(th) using the perturbative QCD technique and the light-cone wave functions of the sigma and omega mesons. The results show that the theoretical value of g(J/psisigmaomega)(th) is within the range of the experimental value of g(J/psisigmaomega). |
