Strong decays of the P_cs(4338) and its high isospin cousin via the QCD sum rules
arxiv(2024)
摘要
In the present work, the strong decays of the newly observed P_cs(4338)
as well as its high isospin cousin P_cs(4460) are studied via the QCD sum
rules. According to conservation of isospin, spin and parity, the hadronic
coupling constants in four decay channels are obtained, then the partial decay
widths are obtained. The total width of the P_cs(4338) coincides with the
experimental data nicely, while the predictions for the P_cs(4460) can be
testified in the future experiment, and shed light on the nature of the
P_cs(4338).
