英文摘要Exclusive decays of X-CJ (J = 0, 2) into phi phi are investigated in the framework of perturbative quantum chromodynamics (pQCD) and P-3(0) quark pair creation model. The results show that these two mechanisms exhibit a quite different behavior in evaluating the decay width for the X-C0 and X-C2. In pQCD method with non-relativistic (NR) approximation, while the calculated X-C2 -> phi phi decay width is comparable with measured one, the result for the X-c0 -> phi phi decay width is suppressed and much smaller than experimental value. However, in P-3(0) quark pair creation model, the situation is reversed: the decay width of X-c0 ->phi phi is greatly enhanced and can reproduce the large measured value, while the contribution to the Xc(2) -> phi phi decay width is small. The results suggest that while the pQCD mechanism is the dominant mechanism for Xc2 ->phi phi decay, the P-3(0) quark pair creation mechanism is the dominant one for X-c0 -> phi phi decay.
