Disentangling the role of the Y(4260) in e+e−→D⁎D¯⁎ and Ds⁎D¯s⁎ via line shape studies
Whether the Y(4260) can couple to open charm channels has been a crucial issue for understanding its nature. The available experimental data suggest that the cross section line shapes of exclusive processes in e+e− annihilations have nontrivial structures around the mass region of the Y(4260). As pa...
