- 論文の詳細を見る
Five-quark (5Q) picture of Λ(1405) is studied using quenched lattice QCD with an exotic 5Q operator of NK type. To discreminate mere NK and Σπ scattering states, Hybrid Boundary Condition (HBC), a flavor-dependent boundary condition, is imposed on the quark fields along spatial direction. 5Q mass m_<5Q>≃1.89GeV is obtained after the chiral extrapolation to the physical quark mass region, which is too heavy to be identified with Λ(1405). Then, Λ(1405) seems neither a pure 3Q state nor a pure 5Q state, and therefore we present an interesting possibility that Λ(1405) is a mixed state of 3Q and 5Q states.
