Description
The resonance of scalar meson is reported to exist in $K-\pi$ system with a mass of about 800 MeV. This meson is called the kappa meson and may constitute the nonet scalar state together with the sigma meson. In the quark model, the mass of scalar meson should be in the higher region. It is very important to investigate the kappa meson by lattice QCD in order to establish the mass spectroscopy of the scalar mesons. Lattice QCD provides a first principal approach for hadron physics and allows us to study non-perturbative aspects of quark-gluon dynamics. We present our recent study of I=1/2 scalar meson by the lattice QCD simulation.
