Lattice QCD studies of s-wave meson-baryon interactions

Abstract

We study the s-wave KN interactions in the isospin I=0, 1 channels and associated exotic state θ+ from 2+1 flavor full lattice QCD simulation for relatively heavy quark mass corresponding to m π=871MeV. The s-wave KN potentials are obtained from the Bethe-Salpeter amplitudes. Potentials in both channels reveal short range repulsions: Strength of the repulsion is stronger in the I=1 potential. The I=0 potential is found to have attractive well at mid range. The KN scattering phase shifts are calculated and compared with the experimental data.
