Search for tetraquark states $X_{cc\bar{s}\bar{s}}$ in $D_s^{+}{D}_s^{+}(D_s^{\ast +}{D}_s^{\ast +})$ final states at Belle

Belle Collaboration, X. Y. Gao, Y. Li +206

A search for double-heavy tetraquark state candidates $X_{cc\bar{s}\bar{s}}$ decaying to $D_s^{+}{D}_s^{+}$ and $D_s^{\ast +}{D}_s^{\ast +}$ is presented for the first time using the…
