Phenomenological study on the decay widths of ${\rm Y}(nS)\to {\bar{d}}^{\ast }(2380)+X$

Chao-Yi Lü, P. Wang, Y. B. Dong +3

The decay widths of ${\rm Y}(nS)$ $\to$ ${\bar{d}}^{\ast }(2380)+X$ with $n=1,2,3$ are studied in a phenomenological way. With the help of crossing symmetry, the decay widths are ob…
