Lattice QCD , Chiral Perturbation Theory
These are the proceedings of the workshop on “Lattice QCD, Chiral Perturbation Theory and Hadron Phenomenology” held at the European Centre for Theoretical Studies in Nuclear Physics and Related Areas from October 2 to 6, 2006. The workshop concentrated on bringing together researchers working in lattice QCD and chiral perturbation theory with the aim of improving our understanding how hadron p...
متن کاملChiral perturbation theory for twisted mass QCD
Quantum Chromodynamics on a lattice with Wilson fermions and a chirally twisted mass term for two degenerate quark flavours is considered in the framework of chiral perturbation theory. The pion masses and decay constants are calculated in next-to-leading order including terms linear in the lattice spacing a. We treat both unquenched and partially quenched QCD. We also discuss the phase structu...
متن کاملQCD sum rules vs . chiral perturbation theory
QCD sum rules are useful tools for studying the spectral properties of hadrons; however, assumptions underlying standard sum-rule analyses can lead to inconsistencies with known results of chiral perturbation theory. This possibility is demonstrated with QCD sum-rule extractions of the nucleon mass and σ term. In both cases, inconsistent chiral behavior leads to an uncertainty in the sum-rule p...
متن کاملMatching Current Correlators in Lattice QCD to Chiral Perturbation Theory
Chiral perturbation theory gives direct and unambiguous predictions for the form of various two-point hadronic correlators at low momentum in terms of a finite set of couplings in a chiral Lagrangian. In this paper we study the feasibility of extracting the couplings in the chiral Lagrangian (through 1-loop order) by fitting two-point correlators computed in lattice QCD to the predicted chiral ...
متن کاملConstraints on Chiral Perturbation Theory Parameters from QCD Inequalities
We explore some of the constraints imposed by positivity of the QCD measure (Weingarten’s inequalities) on the parameters defining chiral perturbation theory. We find, in particular, that 2mq(μ) ≤ B0(μ)Z(μ). The use of further properties of the exact fermion propagator yields information on some higher order parameters. e-mail: [email protected] e-mail: [email protected] e-mail: ...
