Overlap valence quarks on a twisted mass sea: a case study for mixed action Lattice QCD
Krzysztof Cichy, Vincent Drach, Elena Garcia-Ramos +2
We discuss a Lattice QCD mixed action investigation employing Wilson maximally twisted mass sea and overlap valence fermions. Using four values of the lattice spacing, we demonstra…
Lattice Hamiltonian approach to the massless Schwinger model: precise extraction of the mass gap
Krzysztof Cichy, Agnieszka Kujawa-Cichy, Marcin Szyniszewski
We present results of applying the Hamiltonian approach to the massless Schwinger model. A finite basis is constructed using the strong coupling expansion to a very high order. Usi…
Higgs-Yukawa model in chirally-invariant lattice field theory
John Bulava, Philipp Gerhold, Karl Jansen +6
Non-perturbative numerical lattice studies of the Higgs-Yukawa sector of the standard model with exact chiral symmetry are reviewed. In particular, we discuss bounds on the Higgs b…
Non-perturbative renormalization in coordinate space for maximally twisted mass fermions with tree-level Symanzik improved gauge action
Krzysztof Cichy, Karl Jansen, Piotr Korcyl
We present results of a lattice QCD application of a coordinate space renormalization scheme for the extraction of renormalization constants for flavour non-singlet bilinear quark…
Parameters of Heavy Quark Effective Theory from Nf=2 lattice QCD
Benoit Blossier, Michele Della Morte, Patrick Fritzsch +5
We report on a non-perturbative determination of the parameters of the lattice Heavy Quark Effective Theory (HQET) Lagrangian and of the time component of the heavy-light axial-vec…
