The study of possible molecular states of $D_s^{(\ast )}{D}_s^{(\ast )}$ and $B_s^{(\ast )}{B}_s^{(\ast )}$

Hong-Wei Ke, Yan-Liang Shi

Recently the LHCb collaboration reported a new exotic state $T_{cc}^{+}$ which is conjectured to be a molecular state of $D^0{D}^{\ast +}$ (or $D^{\ast 0}{D}^{+}$) theoretically. Belle Collabora…
