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…
Charm quark effects on the strong coupling extracted from the static force
Salvatore Cali, Francesco Knechtli, Tomasz Korzec +1
We compute the fermionic contribution to the strong coupling extracted from the static force in Lattice QCD up to order in perturbation theory. This allows us to sub…
Power corrections from decoupling of the charm quark
Francesco Knechtli, Tomasz Korzec, Björn Leder +1
Decoupling of heavy quarks at low energies can be described by means of an effective theory as shown by S. Weinberg in Ref. [1]. We study the decoupling of the charm quark by latti…
Lattice Quantum Chromodynamics
Francesco Knechtli
This lecture provides an introduction to quantum chromodynamics (QCD) on the lattice. The continuum limit and Monte Carlo simulations are briefly discussed. Different facets of QCD…
