摘要：The phase structure of Nf =2 QCD is studied by lattice simulations. We employ the RG improved
gauge and clover fermion action on 83 ×8, 103 ×10 and 123 ×12 lattices with the anisotropy
x ≡ as/at =2, where as and at are spatial and temporal lattice spacings. We determine the critical
temperature Tc by the Polyakov loop susceptibility. Hadron properties at finite temperature are
also investigated. Our lattice wavefunctions imply pseudoscalar and vector mesons are bound
states even around the phase transition point. We found meson masses near the transition point
do not show significant shifts by thermal effects.
