Two-point functions of quenched lattice QCD in Numerical Stochastic Perturbation Theory. (I) The ghost propagator in Landau gauge
F. Di Renzo, E. -M. Ilgenfritz, H. Perlt +2
This is the first of a series of two papers on the perturbative computation of the ghost and gluon propagators in SU(3) Lattice Gauge Theory. Our final aim is to eventually compare…
Results from 2+1 flavours of SLiNC fermions
W. Bietenholz, V. Bornyakov, N. Cundy +12
QCD results are presented for a 2+1 flavour fermion clover action (which we call the SLiNC action). A method of tuning the quark masses to their physical values is discussed. In th…
Wilson loops in very high order lattice perturbation theory
E. -M. Ilgenfritz, Y. Nakamura, H. Perlt +3
We calculate Wilson loops of various sizes up to loop order for lattice sizes of using the technique of Numerical Stochastic Perturbation Theory in que…
A Non-Perturbative Operator Product Expansion
W. Bietenholz, N. Cundy, M. Goeckeler +8
Nucleon structure functions can be observed in Deep Inelastic Scattering experiments, but it is an outstanding challenge to confront them with fully non-perturbative QCD results. F…
Non-perturbative improvement of stout-smeared three flavour clover fermions
N. Cundy, M. Göckeler, R. Horsley +11
We discuss a 3-flavour lattice QCD action with clover improvement in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links fo…
