Numerical simulations with two flavours of twisted-mass Wilson quarks and DBW2 gauge action
F. Farchioni, P. Hofmann, K. Jansen +9
Discretisation errors in two-flavour lattice QCD with Wilson-quarks and DBW2 gauge action are investigated by comparing numerical simulation data at two values of the bare gauge co…
Probing the topological structure of the QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Overlap fermions implement exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study…
Nf=2 Lattice QCD and Chiral Perturbation Theory
L. Scorzato, F. Farchioni, P. Hofmann +10
By employing a twisted mass term, we compare recent results from lattice calculations of Nf=2 dynamical Wilson fermions with Wilson Chiral Perturbation Theory (WChPT). The final go…
Exact form factors in integrable quantum field theories: the scaling Z(N)-Ising model
H. Babujian, A. Foerster, M. Karowski
A general form factor formula for the scaling Z(N)-Ising model is constructed. Exact expressions for matrix elements are obtained for several local operators. In addition, the comm…
Reconciliation of Statistical Mechanics and Astro-Physical Statistics. The errors of conventional canonical thermostatistics
D. H. E. Gross
Conventional thermo-statistics address infinite homogeneous systems within the canonical ensemble. (Only in this case this is equivalent to the fundamental microcanonical ensemble.…
On Multiple Schramm-Loewner Evolutions
K. Graham
In this note we consider the ansatz for Multiple Schramm-Loewner Evolutions (SLEs) proposed by Bauer, Bernard and Kytola from a more probabilistic point of view. Here we show their…
