Local topological and chiral properties of QCD
Ph. de Forcrand, M. Garcia Perez, J. E. Hetrick +3
To elucidate the role played by instantons in chiral symmetry breaking, we explore their properties in full QCD, around the critical temperature. We study in particular spatial cor…
Domain wall fermions at finite temperature
J. -F. Lagae, D. K. Sinclair
We investigate the properties of domain wall fermions on a set of quenched configurations at non-zero temperature. In particular, we compute the low lying eigenvalues of the DWF op…
Thermodynamics of Lattice QCD with massless quarks and chiral 4-fermion interactions
J. B. Kogut, J. -F. Lagae, D. K. Sinclair
We have simulated lattice QCD with an irrelevant 4-fermion interaction and 2 zero mass quarks. The chiral phase transition is observed to be second order and we discuss extraction…
Improved staggered quark actions with reduced flavour symmetry violations for lattice QCD
J. -F. Lagae, D. K. Sinclair
We introduce a new class of actions for staggered quarks in lattice QCD which significantly reduce flavour symmetry violations in the pion mass spectrum. An action introduced by th…
Thermodynamics of Lattice QCD with 2 Quark Flavours: Chiral Symmetry and Topology
J. -F. Lagae, D. K. Sinclair, J. B. Kogut
We have studied the restoration of chiral symmetry in lattice QCD at the finite temperature transition from hadronic matter to a quark-gluon plasma. By measuring the screening mass…
Topology, fermionic zero modes and flavor singlet correlators in finite temperature QCD
J. B. Kogut, J. -F. Lagae, D. K. Sinclair
We compute the screening correlators in the sigma and eta' flavor singlet channels in finite temperature QCD with 2 light quark flavors. Together with the correlators in the pi and…
