AbstractAbstract
[en] Chiral symmetry breaking is studied in lattice quantum electrodynamics in the quenched approximation by computer-simulation methods. Simulations at zero temperature show that < anti psi psi> in non-zero for all couplings e2 greater than a critical value e2/sub c/. The sensitivity of < anti psi psi> to short-distance features of the lattice Action is studied by simulating variant gauge Actions. Simulations on asymmetric lattices do not reveal significant temperature dependence in the symmetry-breaking dynamics. Subtle effects and limitations of quenched calculations are discussed
