The K Tcc(3875) Interaction: Bound State, Scattering Observables and Correlation Function
Abstract
We investigate the interaction of a kaon with the Tcc(3875) state, evaluating the scattering amplitude and the correlation function of the system within a molecular picture in which the Tcc(3875) is regarded as a D* D bound state. Since the KD* and KD interactions dynamically generate the Ds1(2460) and Ds0*(2317) resonances, respectively, both of which are significantly bound with respect to their corresponding particle thresholds, the KTcc(3875) interaction is found to be strongly attractive, leading to the formation of two bound states with binding energies of about 63 MeV and 51 MeV, respectively, with respect to the KTcc(3875) threshold. We also determine the scattering observables at threshold, including the scattering length and effective range, and calculate the correlation function. The latter exhibits features similar to those found in previous studies of the scattering of an external particle off a dynamically generated resonance of molecular nature.

AB - We investigate the interaction of a kaon with the T_cc(3875) state, evaluating the scattering amplitude and the correlation function of the system within a molecular picture in which the T_cc(3875) is regarded as a D^* D bound state. Since the KD^* and KD interactions dynamically generate the D_s1(2460) and D_s0^*(2317) resonances, respectively, both of which are significantly bound with respect to their corresponding particle thresholds, the KT_cc(3875) interaction is found to be strongly attractive, leading to the formation of two bound states with binding energies of about 63 MeV and 51 MeV, respectively, with respect to the KT_cc(3875) threshold.
