Effective-field theories for heavy quarkonium [PDF]

open access: yesReviews 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.

Two-point functions and S-parameter in QCD-like theories [PDF]

open access: yesJournal of High Energy Physics, 2012
We calculated the vector, axial-vector, scalar and pseudo-scalar two-point functions up to two-loop level in the low-energy effective field theory for three different QCD-like theories. In addition we also calculated the pseudo-scalar decay constant G M.

Effective Theories for QCD-like at TeV Scale [PDF]

open access: yesNuclear and Particle Physics Proceedings, 2016
We study the Effective Field Theory of three QCD-like theories, which can be classified by having quarks in a complex, real or pseudo-real representations of the gauge group.

Limitations on the validity of effective field theory in QCD

Nuclear Physics A, 1991
Abstract 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

2008
Chiral 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 ...
