The chiral limit of the two - flavor lattice Schwinger model with Wilson fermions ∗
We study the 2-flavor lattice Schwinger model with Wilson fermions in the chiral limit. The quark mass is determined using the PCAC definition. We numerically compute the masses of the iso-triplet (π) and iso-singlet particles (η) for different quark masses and compare our results with analytical formulas.

متن کاملHamiltonian lattice quantum chromodynamics at finite density with Wilson fermions
Quantum chromodynamics (QCD) at sufficiently high density is expected to undergo a chiral phase transition. In Lagrangian SU(3) lattice gauge theory, the standard approach breaks down at large chemical potential μ, due to the complex action problem. (QCD at large μ is of particular importance for neutron star or quark star physics). The Hamiltonian formulation of lattice QCD doesn’t encounter s...
متن کاملHamiltonian Lattice QCD with Wilson Fermions at Strong Coupling
Hamiltonian lattice QCD with Wilson fermions is investigated systematically by strongcoupling expansion up to the second order. The effective Hamiltonian is diagonalized by Bogoliubov transformation. The vacuum energy, chiral condensate, pseudo-scalar and vector meson masses are calculated. The comparison with the unitary transformation method by Luo and Chen is also made. The method discussed ...
متن کاملRenormalization of lattice gauge theories with massless Ginsparg Wilson fermions
Using functional techniques, we prove, to all orders of perturbation theory, that lattice vector gauge theories with Ginsparg Wilson fermions are renormalizable. For two or more massless fermions, they satisfy a flavour mixing axial vector Ward identity. It involves a lattice specific part that is quadratic in the vertex functional and classically irrelevant. We show that it stays irrelevant un...
