摘要：

We study the spectrum of H(m) = gamma(5)W(-m) with W(m) being the Wilson-Dirac operator on the lattice with bare mass equal to m. The background gauge fields are generated using the SU(3) Wilson action at beta = 5.7 on an 8(3) x 16 lattice. We find evidence that the spectrum of H(m) is gapless for 1.02 < m < 2.0, implying thar the physical quark is massless in this whole region. (C) 1998 Elsevier Science B.V.
