Lambda_c N interaction from lattice QCD and its application to Lambda_c hypernuclei

We study the Lambda_c - nucleon interaction faithful to S-matrix in QCD on the basis of the HAL QCD method.

In HAL QCD method, Nambu-Bethe-Salpeter wave functions are calculated on the lattice, and potentials are extracted form them.

I will present our results on the 1S0 and 3S1 Lambda_c - nucleon potentials and scattering observables such as phase shifts.

The scattering observables show that the Lambda_c - nucleon interaction is attractive and its spin dependence is weak.

Using the extracted potentials, we also examine possible Lambda_c nuclei by constructing a single-folding potential, which can be studied at J-PARC and FAIR in the future.
