Isospin-breaking corrections to light leptonic decays in lattice QCD+QED at the physical point
Peter Boyle, Matteo Di Carlo, Felix Erben +10
We report on the physical-point RBC/UKQCD calculation of the leading isospin-breaking corrections to light-meson leptonic decays. This is highly relevant for future precision tests…
Near-Physical Point Lattice Calculation of Isospin-Breaking Corrections to
Andrew Zhen Ning Yong, Peter Boyle, Matteo Di Carlo +9
In recent years, lattice determinations of non-perturbative quantities such as and , which are relevant for and , have reached an impressive precision…
Computation of QCD meson screening masses at high temperature
Davide Laudicina, Mattia Dalla Brida, Leonardo Giusti +2
We compute flavor non-singlet meson screening masses in the chiral limit of QCD with quarks. The calculation is carried out at 12 temperatures from GeV up to t…
Non-perturbative renormalization and O-improvement of the non-singlet vector current with Wilson fermions and tree-level Symanzik improved gauge action
Antoine Gerardin, Tim Harris, Harvey B. Meyer
In calculating hadronic contributions to precision observables for tests of the Standard Model in lattice QCD, the electromagnetic current plays a central role. Using a Wilson acti…
A variational method for spectral functions
Tim Harris, Harvey B. Meyer, Daniel Robaina
The Generalized Eigenvalue Problem (GEVP) has been used extensively in the past in order to reliably extract energy levels from time-dependent Euclidean correlators calculated in L…
Non-perturbative improvement of the vector current in Wilson lattice QCD
Tim Harris, Harvey B. Meyer
Many observables of interest in lattice QCD are extracted from correlation functions involving the vector current. If Wilson fermions are used, it is therefore of practical importa…
