The spectroscopic parameters and widths of the axial-vector $$T_{cc:s}^{ \textrm{AV}}$$ scalar $$T_{cc:s}^{\textrm{S}}$$ , $$\widetilde{T}_{cc:s}^{ \textrm{S}}$$ strange partners doubly charmed exotic meson $$T_{cc}^{+}$$ with content $$cc\overline{u}\overline{s}$$ are calculated in framework QCD sum rule method. We model $$T_{cc:s}^{\textrm{AV}}$$ as diquark–antidiquark state composed componen...

Motivated by the recent observation of tetraquark $ T_{cc}^{+}$, we investigate magnetic dipole moments possible single and double strange partners, $T_{QQ \bar q s}$ s s}$, with spin-parity J^{P} = 1^{+}$ means QCD light-cone sum rules. To this end, model these states as diquark-antidiquark different organizations interpolating currents. The results obtained using structures differ from each o...

Abstract We study the S -wave mass spectra of flavor exotic triply-heavy tetraquark states $$cc\bar{c}\bar{q}$$ c ¯ q , $$cc\bar{b}\bar{q}$$ b $$bb\bar{c}\bar{q}$$ and $$bb\bar{b}\bar{q}$$ . adopt a diquark–anti...

In this paper, we investigate the mass spectrum of ground state hidden-charm tetraquark molecular states without strange, with strange and hidden-strange via QCD sum rules in a comprehensive way revisit assignments [Formula: see text], text] scenario consistently based on rules.
