1550-7998=20 Weakly Interacting Massive Particles (WIMPs) of mass m freeze-out at a temperature Tf â€™ m=25, i.e. in the range 400 MeVâ€“ 40 GeV for a particle in the typical mass range 10â€“1000 GeV. Theâ€¦ (More)

A brief review is given of the sign problem in finite density lattice QCD and various attempts to overcome it. To date there is still no solution to this problem which would work for realistic QCD.â€¦ (More)

We present results on the QCD phase diagram for Î¼B â‰¤ Ï€T . Our simulations are performed with an imaginary chemical potential Î¼ = iÎ¼I for which the fermion determinant is positive. On an 83 Ã— 4â€¦ (More)

We determine the static potential for a heavy quark-antiquark pair propagating in Minkowski time at finite temperature, to leading non-trivial order in Hard Thermal Loop resummed perturbation theory.â€¦ (More)

We present an OpenCL-based Lattice QCD application using a heatbath algorithm for the pure gauge case and Wilson fermions in the twisted mass formulation. The implementation is platform independentâ€¦ (More)

Thermalization of a heavy quark near rest is controlled by the correlator of two electric fields along a temporal Wilson line. We address this correlator within real-time, classical latticeâ€¦ (More)

Lattice QCD at finite density suffers from a severe sign problem, which has so far prohibited simulations of the cold and dense regime. Here we study the onset of nuclear matter employing aâ€¦ (More)

Abstract: A three-dimensional effective lattice theory of Polyakov loops is derived from QCD by expansions in the fundamental character of the gauge action, u, and the hopping parameter, Îº, whoseâ€¦ (More)
