Decoupling of charm beyond leading order
Francesco Knechtli, Tomasz Korzec, Björn Leder +1
We study the effective theory of decoupling of a charm quark at low energies. We do this by simulating a model, QCD with two mass-degenerate charm quarks. At leading order the effe…
Impact of dynamical charm quarks
Tomasz Korzec, Francesco Knechtli, Salvatore Cali +2
We compute and compare the continuum limits of several quantities in QCD with and without a dynamical charm quark. We consider both low energy quantities, like the hadronic scales…
Test of the Schrödinger functional with chiral fermions in the Gross-Neveu model
Bjorn Leder
The recently proposed construction of chiral fermions on lattices with boundaries is tested in an interacting theory up to first order of perturbation theory. We confirm that, in t…
The Schroedinger functional for Gross-Neveu models
Bjorn Leder
Gross-Neveu type models with a finite number of fermion flavours are studied on a two-dimensional Euclidean space-time lattice. The models are asymptotically free and are invariant…
Perturbative renormalisation of the chiral Gross-Neveu model
Bjorn Leder, Tomasz Korzec
We study the chiral Gross-Neveu model with Wilson fermions. In the framework of the Schroedinger functional we show that in general not only the bare mass has to be tuned to achiev…
Monte-Carlo simulation of the chiral Gross-Neveu model
Tomasz Korzec, Francesco Knechtli, Ulli Wolff +1
We investigate the two flavor chiral Gross-Neveu model in the Schroedinger functional on the lattice. The procedure necessary to recover chiral symmetry in the continuum limit of t…
