内容記述 | We perform the first study of the static pentaquark (5Q) potential V_<5Q> in SU(3) quenched lattice QCD with 16^3 × 32 and β= 6.0. From the 5Q Wilson loop, V_<5Q> is calculated in a gauge-invariant manner, with the smearing method to enhance the ground-state component. V_<5Q> is well described by the OGE–plus–multi-Y ansatz: a sum of the one-gluon-exchange (OGE) Coulomb term and the multi-Y-type linear term proportional to the minimal total length of the flux tube linking the five quarks. Comparing with Q Q^^- and 3Q potentials, we find a universality of the string tension, σ_<QQ^^->+≃σ_<3Q>≃σ_<5Q> , and the OGE result for Coulomb coefficients. | |||||
