Hadron spectrum, quark masses and decay constants from light overlap fermions on large lattices
D. Galletly, M. Gürtler, R. Horsley +5
We present results from a simulation of quenched overlap fermions with Lüscher-Weisz gauge field action on lattices up to and for pion masses down to MeV. A…
Quark masses from quenched overlap fermions
Martin Gürtler, Thomas Streuer, Gerrit Schierholz +3
We compute light and strange quark masses for quenched overlap fermions at two values of the gauge coupling. The renormalisation is done non-perturbatively. We test the predictions…
Nucleon Structure from Quenched Overlap Fermions
D. Galletly, M. Gürtler, R. Horsley +6
We compute the lowest moments of the nucleon's structure functions using quenched overlap fermions at two different lattice spacings. The renormalisation is done nonperturbatively…
Structure functions and form factors close to the chiral limit from lattice QCD
T. Bakeyev, D. Galletly, M. Göckeler +12
Results for nucleon matrix elements (arising from moments of structure functions) and form factors from a mixture of runs using Wilson, clover and overlap fermions (both quenched a…
Quark spectra and light hadron phenomenology from overlap fermions with improved gauge field action
D. Galletly, M. Gürtler, R. Horsley +8
We present first results from a simulation of quenched overlap fermions with improved gauge field action. Among the quantities we study are the spectral properties of the overlap o…
