| 英文摘要 | In the present work, the hidden-charm decays of Y(4390) are investigated in a D*(D) over bar1 +1 H.c.molecular scenario. We find in this frame the observation of the Y(4390) in the e(+)e(-) -> pi(+)pi(-) h(c) process and the absence of this state in the e(+)e(-) -> pi(+)pi(-) J/psi process are very natural. The partial width of Y(4390) -> pi(+)pi(-) hc could reach up to 1.26 MeV, which is large enough to be observed. The result also indicates that the partial widths of Y(4390) -> eta J/psi and Y(4390) -> eta h(c) are of the same order of magnitude as the one of Y(4390) -> pi(+)pi(-) h(c), which could be tested by the precise measurements at BES III and Belle II. |
