Future applications of the Yang-Mills gradient flow in lattice QCD
Martin Lüscher
The Yang--Mills gradient flow has many interesting applications in lattice QCD. In this talk, some recent and possible future uses of the flow are discussed, emphasizing the underl…
Non-perturbative O(a) improvement of lattice QCD
Martin Luescher, Stefan Sint, Rainer Sommer +2
The coefficients multiplying the counterterms required for O() improvement of the action and the isovector axial current in lattice QCD are computed non-perturbatively, in the q…
Chiral symmetry and O(a) improvement in lattice QCD
Martin Luescher, Stefan Sint, Rainer Sommer +1
The dominant cutoff effects in lattice QCD with Wilson quarks are proportional to the lattice spacing a. In particular, the isovector axial current satisfies the PCAC relation only…
Coordinate space methods for the evaluation of Feynman diagrams in lattice field theory
Martin Luescher, Peter Weisz
We describe an efficient position space technique to calculate lattice Feynman integrals in infinite volume. The method applies to diagrams with massless propagators. For illustrat…
A New Approach to the Problem of Dynamical Quarks in Numerical Simulations of Lattice QCD
Martin Luescher
Lattice QCD with an even number of degenerate quark flavours is shown to be a limit of a local bosonic field theory. The action of the bosonic theory is real and bounded from below…
A Precise Determination of the Running Coupling in the SU(3) Yang-Mills Theory
Martin Luescher, Rainer Sommer, Peter Weisz +1
A non-perturbative finite-size scaling technique is used to study the evolution of the running coupling (in a certain adapted scheme) in the SU(3) Yang-Mills theory. At low energie…
