abstract
Using lattice QCD simulation in the quenched approximation, we study the κ meson, which is ^3P_0 in the quark model, and compare experimental and other lattice data. The κ is the lowest scalar meson with strangeness and constitutes the scalar nonet. The obtained mass is much higher than the recent experimental value, and therefore the κ(800) is difficult to consider as a simple two-body constituent-quark structure, and may have another unconventional structure.
