Extrapolating lattice QCD results using effective field theory [PDF]
Physical Review C, 2020 Lattice simulations are the only viable way to obtain ab-initio Quantum Chromodynamics (QCD) predictions for low energy nuclear physics. These calculations are done, however, in a finite box and therefore extrapolation is needed to get the free space results. Here we use nuclear Effective Field Theory (EFT), designed to provide a low energy description

Effective field theories from QCD [PDF]
Nuclear Physics, Section B, Proceedings Supplements, 1995 We present a method for extracting effective Lagrangians from QCD. The resulting effective Lagrangians are based on exact rewrites of cut-off QCD in terms of these new collective field degrees of freedom. These cut-off Lagrangians are thus ``effective'' in the sense that they explicitly contain some of the physical long-distance degrees of freedom from

Finite volume and partially quenched QCD-like effective field theories [PDF]
Journal of High Energy Physics, 2015 We present a calculation of the meson masses, decay constants and quark-antiquark vacuum expectation value for the three generic QCD-like chiral symmetry breaking patterns $SU(N_F)\times SU(N_F)\to SU(N_F)_V$, $SU(N_F)\to SO(N_F)$ and $SU(2N_F)\to Sp(2 N_F)$ in the effective field theory for these cases.

Effective-field theories for heavy quarkonium [PDF]
Reviews of Modern Physics, 2005 This article reviews recent theoretical developments in heavy-quarkonium physics from the point of view of effective-field theories of QCD. We discuss nonrelativistic QCD and concentrate on potential nonrelativistic QCD.

Limitations on the validity of effective field theory in QCD
Nuclear Physics A, 1991Abstract In the heavy quark, weak confinement limit of QCD hadron properties such as charge radii are easily calculated from the Schrodinger equation. We examine these calculations from the viewpoint of dispersion theory and show how attempts to describe hadronic phenomena entirely in terms of an effective field theory of mesons and baryons can go ...

Hadron Structure and QCD: Effective Field Theory for Lattice Simulations
2008Chiral extrapolations will be essential for many years if one is to connect modern lattice QCD calculations with experiment. Given the enormous efforts made to ensure that the lattice QCD simulations are a rigorous implementation of nonperturbative QCD, it is essential that the chiral extrapolation procedure should also be consistent with all known ...
