The spectrum of radial, orbital and gluonic excitations of charmonium
K. J. Juge, A. O. Cais, M. B. Oktay +3
We present results for the charmonium spectrum from dynamical QCD simulations on anisotropic lattices. Using all-to-all propagators we determine the ground…
Quark-gluon vertex in general kinematics
Ayse Kizilersu, Derek B. Leinweber, Jon-Ivar Skullerud +1
We compute the quark-gluon vertex in quenched lattice QCD, in the Landau gauge using an off-shell mean-field O(a)-improved fermion action. The Dirac-vector part of the vertex is co…
Charmonium spectral functions in two-flavour QCD
G. Aarts, C. R. Allton, R. Morrin +4
We compute charmonium spectral functions in 2-flavour QCD using the maximum entropy method and anisotropic lattices. We find that the S-waves (J/psi and eta_c) survive up to temper…
Dynamical QCD simulations on anisotropic lattices
Richie Morrin, Alan O Cais, Mike Peardon +2
The simulation of QCD on dynamical (Nf=2) anisotropic lattices is described. A method for nonperturbative renormalisation of the parameters in the anisotropic gauge and quark actio…
Deconfinement in dense 2-color QCD
Simon Hands, Seyong Kim, Jon-Ivar Skullerud
We study SU(2) lattice gauge theory with two flavors of Wilson fermion at non-zero chemical potential mu and low temperature on a 8^3x16 system. We identify three regimes along the…
