More than 99% of the mass of the visible universe is made up of protons and neutrons. Both particles are much heavier than their quark and gluon constituents, and the Standard Model of particle physics should explain this difference. We present a full ab initio calculation of the masses of protons, neutrons, and other light hadrons, using lattice quantum chromodynamics. Pion masses down to 190 mega–electron volts are used to extrapolate to the physical point, with lattice sizes of approximately… Expand
Form factors from lattice QCD
Precision computation of hadronic physics with lattice QCD is becoming feasible. The last decade has seen percent-level calculations of many simple properties of mesons, and the last few years haveExpand
Lattice QCD results for the HVP contribution to the anomalous magnetic moments of leptons
We present lattice QCD results by the Budapest-Marseille-Wuppertal (BMW) Collaboration for the leading-order contribution of the hadron vacuum polarization (LOHVP) to the anomalous magnetic momentsExpand
Lattice Gauge Theory and the Origin of Mass
Most of the mass of everyday objects resides in atomic nuclei/ the total of the electrons' mass adds up to less than one part in a thousand. The nuclei are composed of nucleons---protons andExpand
Lattice QCD at the physical point: Light quark masses
Abstract Ordinary matter is described by six fundamental parameters: three couplings (gravitational, electromagnetic and strong) and three masses: the electronʼs ( m e ) and those of the up ( m u )Expand
We review the current status of theories and experiments aiming at an understanding and a determination of the properties of light vector and scalar mesons inside strongly interacting hadronicExpand
Excited spectroscopy of charmed mesons from lattice QCD
A bstractWe present spectra of highly excited D and Ds mesons up to around 3.8 GeV determined using dynamical lattice QCD. We employ novel computational techniques and the variational method with aExpand
Review on the inclusion of isospin breaking effects in lattice calculations
Isospin symmetry is explicitly broken in the Standard Model by the non-zero differences of mass and electric charge between the up and down quarks. Both of these corrections are expected to have aExpand
Finite volume effects for nucleon and heavy meson masses
We apply the resummed version of the Luscher formula to analyze finite volume corrections to the mass of the nucleon and of heavy mesons. We show that by applying the subthreshold expansion of theExpand
Light meson physics from maximally twisted mass lattice QCD
We present a comprehensive investigation of light meson physics using maximally twisted mass fermions for Nf = 2 mass-degenerate quark flavours. By employing four values of the lattice spacing,Expand
Ab initio calculation of the neutron-proton mass difference
The mass difference between neutrons and protons results from the competition between electromagnetic and mass isospin breaking effects and is calculated to high precision using a sophisticated approach that took into account the various forces that exist within a nucleon. Expand

The nucleon mass in Nf=2 lattice QCD: finite size effects from chiral perturbation theory
Abstract In the framework of relativistic SU(2) f baryon chiral perturbation theory we calculate the volume dependence of the nucleon mass up to and including O ( p 4 ). Since the parameters in theExpand
Light hadrons with improved staggered quarks: Approaching the continuum limit
We have extended our program of QCD simulations with an improved Kogut-Susskind quark action to a smaller lattice spacing, approximately 0.09 fm. Also, the simulations with a{approx_equal}0.12 fmExpand
High-precision lattice QCD confronts experiment.
To test the Symanzik-improved staggered-quark discretization formalism, experiment with a variety of nonperturbative calculations in QCD drawn from a restricted set of "gold-plated" quantities finds agreement to within statistical and systematic errors of 3% or less. Expand
Finite-Size Effects in Lattice QCD with Dynamical Wilson Fermions
As computing resources are limited, choosing the parameters for a full lattice QCD simulation always amounts to a compromise between the competing objectives of a lattice spacing as small, quarks asExpand
Signatures of unstable particles in finite volume
Abstract Unstable particles (resonances) occur in QCD, the Higgs model and many other quantum field theories of interest. Since they are a dynamical phenomenon, showing up in scattering processes ofExpand
Confinement of Quarks
A mechanism for total confinement of quarks, similar to that of Schwinger, is defined which requires the existence of Abelian or non-Abelian gauge fields. It is shown how to quantize a gauge fieldExpand
Volume dependence of the energy spectrum in massive quantum field theories
Due to polarization effects, the massM of a stable particle in a quantum field theory enclosed in a large (space-like) box of sizeL and periodic boundary conditions in general differs from itsExpand
