Computation of the strong coupling in QCD with two dynamical flavours
Michele Della Morte, Roberto Frezzotti, Jochen Heitger +3
We present a non-perturbative computation of the running of the coupling alpha_s in QCD with two flavours of dynamical fermions in the Schroedinger functional scheme. We improve ou…
Universality in the Gross-Neveu model
F. Knechtli, T. Korzec, B. Leder +1
We consider universal finite size effects in the large-N limit of the continuum Gross-Neveu model as well as in its discretized versions with Wilson and with staggered fermions. Af…
Cutoff-effects in the spectrum of dynamical Wilson fermions
M. Della Morte, R. Hoffmann, F. Knechtli +1
We investigate the low-lying eigenvalues of the improved Wilson-Dirac operator in the Schroedinger functional with two dynamical quark flavors. At a lattice spacing of approximatel…
Impact of large cutoff-effects on algorithms for improved Wilson fermions
Michele Della Morte, Roland Hoffmann, Francesco Knechtli +1
As a feasibility study for a scaling test we investigate the behavior of algorithms for dynamical fermions in the N_f=2 Schroedinger functional at an intermediate volume of 1 fm^4.…
