Testing the fixed-point QCD action and the construction of chiral currents
P. Hasenfratz, S. Hauswirth, K. Holland +2
We present the first set of quenched QCD measurements using the recently parametrized fixed-point Dirac operator D^FP. We also give a general and practical construction of covarian…
First results from a parametrized Fixed-Point QCD action
P. Hasenfratz, S. Hauswirth, K. Holland +2
We have constructed a new fermion action which is an approximation to the (chirally symmetric) Fixed-Point action, containing the full Clifford algebra with couplings inside a hype…
Chiral measurements with the Fixed-Point Dirac operator and construction of chiral currents
P. Hasenfratz, S. Hauswirth, K. Holland +2
In this preliminary study, we examine the chiral properties of the parametrized Fixed-Point Dirac operator D^FP, see how to improve its chirality via the Overlap construction, meas…
Progress using generalized lattice Dirac operators to parametrize the Fixed-Point QCD action
P. Hasenfratz, S. Hauswirth, K. Holland +3
We report on an ongoing project to parametrize the Fixed-Point Dirac operator for massless quarks, using a very general construction which has arbitrarily many fermion offsets and…
The construction of generalized Dirac operators on the lattice
P. Hasenfratz, S. Hauswirth, K. Holland +3
We discuss the steps to construct Dirac operators which have arbitrary fermion offsets, gauge paths, a general structure in Dirac space and satisfy the basic symmetries (gauge symm…
