Abstract

We systematically explore the S-wave tetraquark systems Qsn̅n̅, QQn̅n̅, QQQ̅Q̅, and sss̅s̅ (Q=c,b; n=u,d) within the constituent quark potential model. We incorporate all K-type Jacobi coordinates in addition to the conventional H-type configurations, optimize the basis expansion via a stochastic parameter generation strategy, and apply the complex scaling method to identify bound and resonant states. Our calculations demonstrate that while conventional H-type configurations suffice for low-lying states such as the Tcc(3875)+ molecular candidate, the inclusion of K-type configurations becomes important for extracting highly excited resonances, allowing higher-energy resonances absent in H-only calculations to be identified. Furthermore, we identify resonance candidates for the Tcs0(2900), X(6900), and X(7200), whereas the absence of fully-strange compact poles below 2.6 GeV challenges the interpretation of ϕ(2170) and X(2370) as S-wave compact s s s̅ s̅ tetraquarks.
