O(a) improved QCD: The 3-loop beta-function, and the critical hopping parameter
A. Bode, H. Panagopoulos, Y. Proestos
We calculate the 3-loop bare -function of QCD, formulated on the lattice with the clover fermionic action. The dependence of our result on the number of colors , the number o…
The three-loop beta-fuction of QCD with the clover action
A. Bode, H. Panagopoulos
We calculate, to 3 loops in perturbation theory, the bare -function of QCD, formulated on the lattice with the clover fermionic action. The dependence of our result on the numbe…
First results on the running coupling in QCD with two massless flavours
Achim Bode, Roberto Frezzotti, Bernd Gehrmann +11
We report on the non-perturbative computation of the running coupling of two-flavour QCD in the Schr"odinger functional scheme. The corresponding Lambda-parameter, which describes…
First experiences with HMC for dynamical overlap fermions
Achim Bode, Urs M. Heller, Robert G. Edwards +1
We describe an HMC algorithm for dynamical overlap fermions which makes use of their good chiral properties. We test the algorithm in the Schwinger model. Topological sectors are r…
Two Loop Computation of the Schroedinger Functional in Lattice QCD
Achim Bode, Peter Weisz, Ulli Wolff
We compute the Schroedinger functional (SF) for the case of lattice QCD with Wilson fermions (with and without SW improvement) at two-loop order in lattice perturbation theory. Thi…
Two loop lattice expansion of the Schroedinger functional coupling in improved QCD
A. Bode, P. Weisz, U. Wolff
The contributions of the improved fermion action of Sheikholeslami and Wohlert to the two loop coefficient of the expansion of the Schroedinger functional coupling in terms of the…
