![]() We also discuss the quark-mass and channel dependence of the q̄-q potentials. The derived potentials at each quark mass in both channels show linear plus Coulomb form. We calculate the q̄-q NBS wave functions in pseudo-scalar and vector channels for several quark masses. With the use of a method which has been recently developed in the derivation of nuclear forces from lattice QCD, we derive the q̄-q potentials from the NBS wave functions. We also discuss the quark-mass and channel dependence of the q̄-q potentials.ĪB - Quark-anti-quark (q̄-q) potentials with finite quark masses are studied from the q̄-q Nambu-Bethe-Salpeter (NBS) wave functions in quenched lattice QCD. The derived potentials at each quark mass in both channels show linear plus Coulomb form. Finally, we discuss one of the puzzles in hadron spectroscopy, why we haven’t seen any exotic states made of the quantum numbers of ve quarks (pentaquark) or two quark plus a gluon. ![]() N2 - Quark-anti-quark (q̄-q) potentials with finite quark masses are studied from the q̄-q Nambu-Bethe-Salpeter (NBS) wave functions in quenched lattice QCD. ![]() ![]() T1 - Quark-anti-quark potentials from nambu-bethe-salpeter amplitudes on lattice ![]()
