Non-perturbative renormalization by decoupling
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +3
We propose a new strategy for the determination of the QCD coupling. It relies on a coupling computed in QCD with degenerate heavy quarks at a low energy scale $…
Scale setting for QCD with Nf=3+1 dynamical quarks
Roman Höllwieser, Francesco Knechtli, Tomasz Korzec
We present first results of the scale setting for QCD with Nf=3+1 dynamical quarks on the lattice. We use a recently proposed massive renormalization scheme with a non-perturbative…
Constrained Hybrid Monte Carlo algorithms for gauge-Higgs models
Michael Günther, Roman Höllwieser, Francesco Knechtli
We develop Hybrid Monte Carlo (HMC) algorithms for constrained Hamiltonian systems of gauge- Higgs models and introduce a new observable for the constraint effective Higgs potentia…
How much do charm sea quarks affect the charmonium spectrum?
Salvatore Cali, Francesco Knechtli, Tomasz Korzec
The properties of charmonium states are or will be intensively studied by the B-factories Belle II and BESIII, the LHCb and PANDA experiments and at a future Super-c-tau Factory. P…
Charmonium and exotics from lattice QCD
Francesco Knechtli
We review selected lattice results on the charmonium spectrum and first attempts to search for the existence of exotic states. The hadro-quarkonium model was proposed to interpret…
String breaking by light and strange quarks in QCD
John Bulava, Ben Hörz, Francesco Knechtli +4
The energy spectrum of a system containing a static quark anti-quark pair is computed for a wide range of source separations using lattice QCD with dynamical fla…
