Hadron Spectrum in a Two-Colour Baryon-Rich Medium
Simon Hands, Peter Sitch, Jon-Ivar Skullerud
The hadron spectrum of SU(2) lattice gauge theory with two flavours of Wilson quark is studied on an 8^3x16 lattice using all-to-all propagators, with particular emphasis on the de…
The SF running coupling with four flavours of staggered quarks
P. Perez-Rubio, S. Sint
In order to study the running coupling in four-flavour QCD, we review the set-up of the Schrödinger functional (SF) with staggered quarks. Staggered quarks require lattices which,…
The flavour projection of staggered fermions and the quarter-root trick
Steven Watterson
It is shown that the flavour projection of staggered fermions can be written as a projection between the fields on four separate, but parallel, lattices, where the fields on each a…
The chiral and flavour projection of Dirac-Kahler fermions in the geometric discretization
Steven Watterson
It is shown that an exact chiral symmetry can be described for Dirac-Kahler fermions using the two complexes of the geometric discretization. This principle is extended to describe…
Unquenching effects in the quark and gluon propagator
Waseem Kamleh, Patrick O. Bowman, Derek B. Leinweber +2
In this work we examine the Fat-Link Irrelevant Clover (FLIC) overlap quark propagator and the gluon propagator on both dynamical and quenched lattices. The tadpole-improved Lusche…
Charmonium at high temperature in two-flavor QCD
Gert Aarts, Chris Allton, Mehmet Bugrahan Oktay +2
We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves (J/psi and eta_c) survive up…
