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 ...

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.

PHENOMENOLOGY FROM LATTICE QCD [PDF]
Lepton-Photon 01, 2002 I review two subject in which lattice simulations are making, or can make in the future, a significant contribution to particle physics phenomenology. The first subject is the evaluation of quantities which enter into the determination of the vertex A of the unitarity triangle from experimental measurements of decay rates and mixing amplitudes.

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.

Lattice QCD and neutrino-nucleus scattering [PDF]
European Physical Journal A, 2019 This document is one of a series of white papers from the USQCD Collaboration. Here, we discuss opportunities for Lattice QCD in neutrino-oscillation physics, which inevitably entails nucleon and nuclear structure.

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 $16^3 \times 32$

Exploring Partonic Structure of Hadrons Using ab initio Lattice QCD Calculations. [PDF]
Physical Review Letters, 2017 Following our previous proposal, we construct a class of good "lattice cross sections" (LCSs), from which we can study the partonic structure of hadrons from ab initio lattice QCD calculations. These good LCSs, on the one hand, can be calculated directly

Inclusive Semileptonic Decays from Lattice QCD. [PDF]
Physical Review Letters, 2020 We develop a method to compute the inclusive semileptonic decay rate of hadrons fully nonperturbatively using lattice QCD simulations. The sum over all possible final states is achieved by a calculation of the forward-scattering matrix elements on the ...

The hadronic vacuum polarization contribution to the muon g − 2 from lattice QCD [PDF]
Journal of High Energy Physics, 2017 We present a calculation of the hadronic vacuum polarization contribution to the muon anomalous magnetic moment, aμhvp, in lattice QCD employing dynamical up and down quarks. We focus on controlling the infrared regime of the vacuum polarization function.

Electrical conductivity of the quark-gluon plasma: perspective from lattice QCD [PDF]
European Physical Journal A, 2020 A discussion on the electrical conductivity of the quark-gluon plasma as determined by lattice QCD is given. After a reminder of basic definitions and expectations, various methods for spectral reconstruction are reviewed, including the use of Ansätze ...
