✦ Synopsis

The infrared properties of lattice Landau gauge QCD of SU(3) are studied by measuring gluon propagator, ghost propagator, QCD running coupling and Kugo-Ojima parameter of /3 = 6.0, 164, 244, 324 and p = 6.4, 324, 484 lattices. We study Gribov copy problem by parallel tempering (PT) gauge fixing of p = 2.2, 164 SU(2) configurations. Rather unexpected features of the unique gauge(fundamental modular gauge, FMG) a,re observed in relation of physical values vs the optimizing function.

The infrared behaviour of QCD in the Landau gauge is studied in 244 and 324 lattices by measuring the Kugo-Ojima parameter, gluon propagator, ghost propagator and the QCD running coupling. The Kugo-Ojima parameter c remains about 0.8 instead of the expectation value 1. We observe infrared suppressio

We study hybrid mesons from the clover and improved gauge actions at /3 = 2.6 on the anisotropic 123 x 36 lattice using our PC cluster. We estimate the mass of 1 -+ light quark hybrid as well as the mass of the charmonium hybrid. The improvement of both quark and gluonic actions, first applied to th
