We report a project to study scalar particles by lattice QCD simulations. After a brief introduction of the current situation of lattice study of the sigma meson, we describe our numerical simulations of scalar mesons, σ and κ. We observe a low sigma mass, mπ < mσ ≤ mρ, for which the disconnected diagram plays an important role. For the kappa meson, we… CONTINUE READING
