Description
The S-wave interactions between doubly charmed baryons ($\Xi_{cc}, \Omega_{cc}$) and Goldstone bosons ($\pi, K, \bar{K}$) are studied using lattice QCD on $N_f=2+1$ CLQCD ensembles ($a = 0.07746$ fm, $M_\pi \simeq 210$ and 300 MeV). By applying Lüscher's method to the finite-volume spectra, we extract scattering lengths and effective ranges for four single-channel systems free of disconnected diagrams: $I=1/2$ $\Omega_{cc}\bar{K}$, $I=1$ $\Xi_{cc}K$, $I=0$ $\Xi_{cc}K$, and $I=3/2$ $\Xi_{cc}\pi$. These results show good agreement with baryon chiral perturbation theory.
