[2605.05799] $T^a_{c\bar{s}0}(2900)$, $T_{cs0}^*(2900)^0$, and other singly heavy tetraquark states Skip to main content Search Submit Donate Log in High Energy Physics - Phenomenology arXiv:2605.05799 (hep-ph) [Submitted on 7 May 2026 ( v1 ), last revised 25 Aug 2026 (this version, v2)] Title: $T^a_{c\bar{s}0}(2900)$, $T_{cs0}^*(2900)^0$, and other singly heavy tetraquark states Authors: Zi-Long Man , Yu-Nan Liu , Yan-Rui Liu View PDF HTML (experimental) Abstract: 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 the $X(4140)$ is the lowest $J^{PC}=1^{++}$ $cs\bar{c}\bar{s}$ tetraquark and use this state as a reference to determine the mass splittings. According to the obtained results, we also estimate the rearrangement decay widths of the tetraquarks within a simple scheme. We find that the recently observed states $T^a_{c\bar{s}0}(2900)^{++/0}$ and $T_{cs0}^*(2900)^0$ by the LHCb Collaboration can be consistently interpreted as the second highest $I(J^P)=1(0^+)$ $cn\bar{s}\bar{n}$ ($n=u,d$) and the higher $I(J^P)=0(0^+)$ $cs\bar{n}\bar{n}$ tetraquark states, respectively. We predict several narrow tetraquark candidates: the lowest $cn\bar{s}\bar{n}$ and $cs\bar{n}\bar{n}$ with $I(J^P)=0(0^+)$ and $0(1^+)$, and their bottom counterparts. The obtained information from mass spectrum and rearrangement decay properties will help search for the new singly heavy tetraquark states.
