Recent results on the running coupling in QCD with two massless flavours
M. Della Morte, R. Frezzotti, J. Heitger +4
We report on the latest results on the running coupling of two flavour QCD in the Schrödinger functional scheme. Results for the step scaling function are obtained from simulations…
Non-perturbative determination of Z_A^{stat} in quenched QCD
Jochen Heitger, Martin Kurth, Rainer Sommer
We non-perturbatively calculate the renormalization factor of the static axial vector current in O(a) improved quenched lattice QCD. Its scale dependence is mapped out in the Schro…
Non-perturbative scale evolution of four-fermion operators
M. Guagnelli, J. Heitger, C. Pena +2
We apply the Schroedinger Functional (SF) formalism to determine the renormalisation group running of four-fermion operators which appear in the effective weak Hamiltonian of the S…
