Radiative corrections to decay amplitudes in lattice QCD

Davide Giusti, Vittorio Lubicz, Guido Martinelli +4

The precision of lattice QCD computations of many quantities has reached such a precision that isospin-breaking corrections, including electromagnetism, must be included if further…

Determination of the quark condensate from heavy-light current-current correlators in full lattice QCD

C. T. H. Davies, K. Hornbostel, J. Komijani +4

We derive the Operator Product Expansion whose vacuum expectation value gives the time-moments of the pseudoscalar heavy-light current-current correlator up to and including terms…

$Z_{S} / Z_{P}$ from three-flavour lattice QCD

Jochen Heitger, Fabian Joswig, Anastassios Vladikas

We report on advances in the non-perturbative determination of the ratio $Z_{S} / Z_{P}$ of the pseudoscalar to the scalar renormalization constants in three-flavour lattice QCD with Wil…

Simulating twisted mass fermions at physical light, strange and charm quark masses

Constantia Alexandrou, Simone Bacchio, Panagiotis Charalambous +11

We present the QCD simulation of the first gauge ensemble of two degenerate light quarks, a strange and a charm quark with all quark masses tuned to their physical values within th…

Higher-order hadronic-vacuum-polarization contribution to the muon g-2 from lattice QCD

Bipasha Chakraborty, Christine T. H. Davies, Jonna Koponen +2

We introduce a new method for calculating the $O (α^{3})$ hadronic-vacuum-polarization contribution to the muon anomalous magnetic moment from $ab - ini t i o$ lattice QCD. We firs…

Euclidean versus Minkowski short distance

Giancarlo Rossi, Massimo Testa

In this note we reexamine the possibility of extracting parton distribution functions from lattice simulations. We discuss the case of quasi-parton distribution functions, the poss…

Gauge invariant determination of charged hadron masses

Martin Hansen, Biagio Lucini, Agostino Patella +1

In this paper we show, for the first time, that charged-hadron masses can be calculated on the lattice without relying on gauge fixing at any stage of the calculations. In our simu…

Non-perturbative quark mass renormalisation and running in $N_{f} = 3$ QCD

Isabel Campos, Patrick Fritzsch, Carlos Pena +3

We determine from first principles the quark mass anomalous dimension in Nf=3 QCD between the electroweak and hadronic scales. This allows for a fully non-perturbative connection o…

Non-Perturbative Renormalisation and Running of BSM Four-Quark Operators in $N_{f} = 2$ QCD

Petros Dimopoulos, Gregorio Herdoíza, Mauro Papinutto +3

We perform a non-perturbative study of the scale-dependent renormalisation factors of a complete set of dimension-six four-fermion operators. The renormalisation-group (RG) running…
