QCD with rooted staggered fermions
In this talk, I will give an overview of the theoretical status of staggered Lattice QCD with the “fourth-root trick.” In this regularization of QCD, a separate staggered quark field is used for each physical flavor, and the inherent four-fold multiplicity that comes with the use of staggered fermions is removed by taking the fourth root of the staggered determinant for each flavor. At nonzero ...
متن کاملAdjoint Fermions Induce QCD
We propose to induce QCD by fermions in the adjoint representation of the gauge group SU(Nc) on the lattice. We consider various types of lattice fermions: chiral, Kogut–Susskind and Wilson ones. Using the mean field method we show that a first order large-N phase transition occurs with decreasing fermion mass. We conclude, therefore, that adjoint fermions induce QCD. We draw the same conclusio...
متن کاملLattice QCD with fixed topology
The overlap Dirac operator, which satisfies the Ginsparg-Wilson relation, realizes exact chiral symmetry on the lattice. It also avoids fermion doubling but its locality and smoothness are subtle. In fact, the index theorem on the lattice implies that there are certain points where the overlap Dirac operator has discontinuities. Aside from the theoretical subtleties, this non-smoothness also ra...
متن کاملQCD hadron spectrum with domain wall fermions
The domain wall fermions (DWF) formalism[1][2] uses an extra space-time dimension to separate the chiral limit from the continuum limit. In this paper, we report a study of the hadron spectrum obtained from both quenched and dynamical DWF. Our conventions are: mf is the 4-d bare quark mass that explicitly mixes the two chiralities on the domain walls, Ls is the extent of lattice in the fifth di...
متن کاملQCD Thermodynamics with Domain Wall Fermions
We present our recent studies of the pseudo-critical temperature, Tc, of QCD using domain wall fermions. Domain wall fermions have the advantage that they preserve exact SU(2) chiral symmetry at finite lattice spacing in the limit that Ls → ∞. The RBC Collaboration has performed a set of dynamical calculations at Ls = 32 and Nt = 8 using the Iwasaki gauge action with two light quarks (mla = 0.0...
