英文摘要 | Apart from the charmful decay channels of Y(4260), the charmless decay channels of Y(4260) also provide us a good platform to study the nature and the decay mechanism of Y(4260). In this paper, we propose to probe the structure of Y(4260) through the charmless decays Y(4260) -> VP via intermediate D-1(D) over bar +c.c. meson loops, where V and P stand for light vector and pseudoscalar mesons, respectively. Under the molecule ansatz of Y(4260), the predicted total branching ratio BRVP for all Y(4260) -> VP processes are about (0.34(-0.23)(+0.32t)% to (0.75-(+0.72)(0.52))% with the cutoff parameter alpha=2-3. Numerical results show that the intermediate D-1<(D)$over bar>+c.c. meson loops may be a possible transition mechanism in the Y(4260) -> VP decays. These predicted branching ratios are the same order to that of Y(4260) -> Z(c)(+) (3900)pi(-), which may be an evidence of D1D molecule and can be examined by the forthcoming BESIII data in the near future. |
