| 英文摘要 | The internal structure of the charm-strange mesons D-s0*(2317) and D-s1(2460) are the subject of intensive studies. Their widths are small because they decay dominantly through isospin-breaking hadronic channels D-s0*(2317)(+) (->) D-s(+) pi(0) and D-s1 (2460)(+)-> D-s* pi(0). The D-s1(2460) can also decay into the hadronic final states D(s)(+)pp, conserving isospin. In that case there is, however, a strong suppression from phase space. We study the transition D-s1(2460)+ D(s)(+)p(+)p(-) in the scenario that the Ds1(2460) is a D*K hadronic molecule. The pp final state interaction is taken into account through dispersion relations. We find that the ratio of the partial widths of the G(D-s1 2460(+) -> D-s(+)pi(+)pi(-) ) G(D-s1 (2460)(+) -> D-s*+ pi(0) ) obtained in the molecular picture is consistent with the existing experimental measurement. More interestingly, we demonstrate that the pi(+)pi(-) invariant mass distribution shows a double bump structure, which can be used to disentangle the hadronic molecular picture from the compact state picture for the D-s1(2460)(+). Predictions on the B-s1(0) -> B-s(0) pi(+) pi(-) are also made. |
