Investigations on the charmless decays of Y(4260)

  • 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 D1D+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+0.23)% to (0.75-0.52+0.72)% with the cutoff parameter α=2-3. Numerical results show that the intermediate m D1D+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)→Zc+(3900)π-, which may be an evidence of D1D molecule and can be examined by the forthcoming BESⅢ data in the near future.

Investigations on the charmless decays of Y(4260)

    Corresponding author: LI Gang,
    Corresponding author: AN Chun-Sheng,

Abstract: 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 D1D+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+0.23)% to (0.75-0.52+0.72)% with the cutoff parameter α=2-3. Numerical results show that the intermediate m D1D+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)→Zc+(3900)π-, which may be an evidence of D1D molecule and can be examined by the forthcoming BESⅢ data in the near future.
