Spectrum of $[cq][\bar{s}\bar{q}]$ tetraquarks: Nature of $D_{s0}^{\ast }(2317)$, $D_{s1}(2460)$ and $T_{c\bar{s}0}^{\ast }(2900)$

Zhi-Yuan Chen, Zhe-Hao Cao, You-You Lin +2

Motivated by the recent observations of exotic open-charm tetraquark candidates \(T^a_{c\bar{s}0}(2900)^{++}\) and \(T^a_{c\bar{s}0}(2900)^{0}\), we systematically calculate the ma…
