Abstract

We probe the existence of the Λc3^3_{\Lambda_c}H where the NΛcN\Lambda_c potentials are derived from the quark-delocalization color-screening model (QDCSM). The NΛcN\Lambda_c system is studied and the NΛcN\Lambda_c scattering length so as the effective range are obtained in the QDCSM. We construct effective Gaussian-type NΛcN\Lambda_c potentials which reproduce the NΛcN\Lambda_c scattering data given by the QDCSM. By solving the NNΛcNN\Lambda_c three body Schr\"odinger equation with the Gaussian expansion method, we calculate the energies of the Λc3^3_{\Lambda_c}H with isospin I=0I=0, JP=1/2+J^P=1/2^+ and I=0I=0, JP=3/2+J^P=3/2^+ under different color screening parameter μ\mu. The JP=1/2+J^P=1/2^+ and JP=3/2+J^P=3/2^+ states are both bound when the color screening parameter μ\mu is set to 1.0 or 1.2, where the JP=1/2+J^P=1/2^+ state is bound by 0.080.850.08\sim0.85 MeV and the JP=3/2+J^P=3/2^+ state is bound by 0.151.310.15\sim1.31 MeV with respect to the deuteron-Λc\Lambda_c threshold.
