Stochastic quantization at finite chemical potential
Gert Aarts, Ion-Olimpiu Stamatescu
A nonperturbative lattice study of QCD at finite chemical potential is complicated due to the complex fermion determinant and the sign problem. Here we apply the method of stochast…
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…
Determination of the running coupling in pure SU(4) Yang-Mills theory
Biagio Lucini, Gregory Moraitis
The Schrodinger functional is used to define a renormalised coupling for pure SU(4) Yang-Mills theory, with Wilson action and suitably selected boundary conditions on the link fiel…
Transport and spectral functions in high-temperature QCD
Gert Aarts
The current status of transport coefficients in relativistic field theories at high temperature is reviewed. I contrast weak coupling results obtained using kinetic theory/diagramm…
Baryon currents in the C-broken phase of QCD
Biagio Lucini, Agostino Patella, Claudio Pica
In a space with some sufficiently small compact dimension (with non-trivial cycles) and with periodic boundary conditions for the fermions, the charge conjugation (C), spatial pari…
G_2 gauge theory at finite temperature
Guido Cossu, Massimo D'Elia, Adriano Di Giacomo +2
The gauge group being centreless, gauge theory is a good laboratory for studying the role of the centre of the group for colour confinement in Yang-Mills gauge theories. In t…
