$D_{s0}(2317)$ as a tetraquark state with QCD sum rules in heavy quark limit

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/182702In this article, we take the point of view that the charmed scalar meson $D_{s0}(2317)$ be a tetraquark state and devote to calculate its mass within the framework of the QCD sum rules approach in the heavy quark limit. The numerical values for the mass of the $D_{s0}(2317)$ are consistent with the experimental data, there must be some tetraquark component in the scalar meson $D_{s0}(2317)$. Detailed discussions about the threshold parameter and Borel parameter for the multiquark states are also presented.9 pages, 1 figure, third versionHigh Energy Physics - Phenomenology$D_{s0}(2317)$ as a tetraquark state with QCD sum rules in heavy quark limittext
