| 内容記述 | We study three-quark and multi-quark potentials in SU(3) lattice QCD. From accurate calculations for more than 300 different patterns of 3Q systems, the static ground-state 3Q potential Vg����s���� 3Q is found to be well described by the Coulomb plus Y-type linear potential (Y-Ansatz) within 1%-level deviation. As a clear evidence for Y-Ansatz, Y-type flux-tube formation is actually observed on lattices in maximally-Abelian projected QCD. For about 100 patterns of 3Q systems, we perform accurate calculations for the 1st excited-state 3Q potential Ve����s���� 3Q by diagonalizing the QCD Hamiltonian in presence of three quarks, and find a large gluonic-excitation energy ΔE3Q ����Ve����s���� 3Q Vg����s���� 3Q of about 1 GeV, which gives a physical reason on success of the quark model. ΔE3Q is found to be reproduced by “inverse Mercedes Ansatz”, which indicates a complicated bulk excitation for the gluonic-excitation mode. We study also tetra-quark and penta-quark potentials in lattice QCD, and find that they are well described by the OGE Coulomb plus multi-Y type linear potential, which supports the flux-tube picture even for multi-quarks. Finally, narrow decay width of low-lying penta-quark baryons is discussed in terms of the QCD string theory. | |||||
