Abstract

Newly, first-principles lattice QCD results at the physical pion mass, mπ137.1 m_\pi \backsimeq 137.1 MeV, have been reported by the HAL QCD Collaboration for the S-wave interaction between the nucleon (NN) and the triply charmed Omega baryon (Ωccc\Omega_{ccc}). The NΩcccN\Omega_{ccc} potentials in the spin-1 (3S1) \left(^{3}S_{1}\right) and spin-2 (5S2) \left(^{5}S_{2}\right) channels were derived and found to be attractive, though no two-body bound state was supported in these channels. The present work investigates the NNΩcccNN\Omega_{ccc} three-body system using the Malfliet-Tjon NNNN potential. Analyses of spin-1, spin-averaged, and spin-2 NΩcccN\Omega_{ccc} channels (at Euclidean times 16, 17, 18) reveal a three-body bound state only for the d-Ωccc\Omega_{ccc} configuration with spin (0)1/2+(0)1/2^{+} and t/a=16t/a=16. Its binding energy (B3=2.255B_3 = -2.255 MeV) lies slightly below the deuteron's (Bd=2.23B_d = -2.23 MeV). Other parameter sets do not yield a bound state, and complex scaling analysis indicates these configurations correspond to virtual states rather than resonances. The Coulomb potential's role was also examined to differentiate charged states.
