Continuum Limit of Overlap Valence Quarks on a Twisted Mass Sea
Krzysztof Cichy, Gregorio Herdoiza, Karl Jansen
We study a lattice QCD mixed action with overlap valence quarks on two flavours of Wilson maximally twisted mass sea quarks. Employing three different matching conditions to relate…
Higgs boson mass bounds in the presence of a very heavy fourth quark generation
P. Gerhold, K. Jansen, J. Kallarackal
We study the effect of a potential fourth quark generation on the upper and lower Higgs boson mass bounds. This investigation is based on the numerical evaluation of a chirally inv…
Critical slowing down and error analysis in lattice QCD simulations
Stefan Schaefer, Rainer Sommer, Francesco Virotta
We study the critical slowing down towards the continuum limit of lattice QCD simulations with Hybrid Monte Carlo type algorithms. In particular for the squared topological charge…
Probing the chiral regime of Nf=2 QCD with mixed actions
Fabio Bernardoni, Nicolas Garron, Pilar Hernandez +2
We report on our first experiences with a mixed action setup with overlap valence quarks and non-perturbatively O(a) improved Wilson sea quarks. For the latter we employ CLS Nf=2 c…
HQET at order 1/m: III. Decay constants in the quenched approximation
Benoît Blossier, Michele Della Morte, Nicolas Garron +4
We report on the computation of the meson decay constant in Heavy Quark Effective Theory on the lattice. The next to leading order corrections in the HQET expansion are inclu…
Computing K and D meson masses with N_f = 2+1+1 twisted mass lattice QCD
ETM Collaboration, Remi Baron, Philippe Boucaud +13
We discuss the computation of the mass of the K and D mesons within the framework of N_f = 2+1+1 twisted mass lattice QCD from a technical point of view. These quantities are essen…
