$T_{c\bar{s}0}^a(2900)$, $T_{cs0}^{\ast }(2870{)}^0$, and other singly-heavy tetraquark states

Zi-Long Man, Yu-Nan Liu, Yan-Rui Liu

We systematically study the mass spectra of $S$-wave singly-heavy tetraquark states $Qq\bar{q}\bar{q}$ ($Q=c,b$; $q=u,d,s$) in a mass splitting model. We adopt the assumption that…
