Determining the width of $$D_{s0}^{*}(2317)$$ by using $$T_{c\bar{s}0}^{a}(2327)$$ in a molecular frame
Abstract
Abstract Motivated by the recent observation of the open-charm tetraquark $$T_{c\bar{s}0}^{a}(2327)$$ T c s ¯ 0 a ( 2327 ) by the LHCb Collaboration, as well as results from Lattice QCD calculations, we consider the $$T_{c\bar{s}0}^{a}(2327)$$ T c s ¯ 0 a ( 2327 ) and the $$D_{s0}^{*}(2317)$$ D s 0 ∗ ( 2317 ) as DK molecular states, with $$I(J^{P})$$ I ( J P ) equal to $$1(0^{+})$$ 1 ( 0 + ) and $$0(0^{+})$$ 0 ( 0 + ) , respectively, and we investigate their strong decay behavior in an effective Lagrangian approach. Within the model parameter range, we can reproduce the $$T_{c\bar{s}0}^{a}(2327)$$ T c s ¯ 0 a ( 2327 ) experimental decay width, with the assumption that the $$D_{s}^{+}\pi ^{0}$$ D s + π 0 is the dominant decay channel of the $$T_{c\bar{s}0}^{a+}(2327)$$ T c s
