Dispersive determination of the HVP contribution to the muon g − 2 [PDF]
EPJ Web of Conferences, 2023 The determination of hadronic vacuum polarization (HVP) from e+e− → hadrons cross-section data, in the energy region relevant for the anomalous magnetic moment of the muon, has recently been challenged by lattice-QCD calculations, especially for the ...

Electromagnetic and spin polarisabilities in lattice QCD [PDF]
, 2006 We discuss the extraction of the electromagnetic and spin polarisabilities of nucleons from lattice QCD. We show that the external field method can be used to measure all the electromagnetic and spin polarisabilities including those of charged particles.

Data-driven evaluations of Euclidean windows to scrutinize hadronic vacuum polarization
Physics Letters B, 2022 In this paper, we discuss how windows in Euclidean time can be used to isolate the origin of potential conflicts between evaluations of the hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon in lattice QCD and ...

Computing the magnetic field response of the proton [PDF]
EPJ Web of Conferences, 2020 Background field methods offer an approach through which fundamental non-perturbative hadronic properties can be studied. Lattice QCD is the only ab initio method with which Quantum Chromodynamics can be studied at low energies; it involves numerically ...

Calculation of the nucleon axial charge in lattice QCD [PDF]
, 2006 Protons and neutrons have a rich structure in terms of their constituents, the quarks and gluons. Understanding this structure requires solving Quantum Chromodynamics (QCD). However QCD is extremely complicated, so we must numerically solve the equations

The effect of sea quarks on the mass of the charm quark from Lattice QCD [PDF]
, 2005 We compute the mass of the charm quark using both quenched and dynamical lattice QCD calculations. We examine the effects of mass dependent lattice artifacts by comparing two different formalisms for the heavy quarks.

Lattice analysis for the energy scale of QCD phenomena [PDF]
, 2008 We formulate a new framework in lattice QCD to study the relevant energy scale of QCD phenomena. By considering the Fourier transformation of link variable, we can investigate the intrinsic energy scale of a physical quantity nonperturbatively.

First Evidence of $N_f$-Dependence in the QCD Interquark Potential [PDF]
, 1996 We present a lattice calculation of the interquark potential between static quarks in a ``full'' QCD simulation with 2 flavours of dynamical Wilson-quarks at three intermediate sea-quark masses. We work at $\beta = 5.6$ on lattice size of $16^3 \times 32$
