Determining the low energy parameters of Wilson Chiral Perturbation Theory
We report preliminary results of a Wilson Chiral Perturbation Theory (WChPT) analysis of twisted mass lattice QCD data. The quenched data, previously published by two different groups, was generated with two definitions for the critical quark mass and shows a strong non-linear quark mass dependence for small quark masses for the pion mass definition (“bending phenomenon”). We find that WChPT de...
متن کاملLow-Energy Constants from Resonance Chiral Theory
I discuss the recent attempts to build an effective chiral Lagrangian incorporating massive resonance states. A useful approximation scheme to organize the resonance Lagrangian is provided by the large-NC limit of QCD. Integrating out the resonance fields, one recovers the usual chiral perturbation theory Lagrangian with explicit values for the low-energy constants, parameterized in terms of re...
متن کاملResonance Contributions to the Electromagnetic Low Energy Constants of Chiral Perturbation Theory
The effective chiral Lagrangian of the strong and electromagnetic interactions of the pseudoscalar mesons at low energies depends on a set of low energy constants. We determine the contributions to the electromagnetic coupling constants at order O(ep), which arise from resonances within a photon loop. We give some implications of our results, in particular we discuss in detail the effects on th...
متن کاملLow Energy Constants of Chiral Perturbation Theory from the Instanton Vacuum
In the framework of the instanton vacuum model we make expansion over the current mass m and number of colors Nc and evaluate O(1/Nc, m, m/Nc, m lnm/Nc)corrections to the dynamical quark mass M , the quark condensate 〈q̄q〉, the pion mass Mπ and decay constant Fπ. We found the SU(2) χPT low-energy constants l̄3, l̄4 in a good correspondence with the phenomenology and lattice calculations. Introduct...
متن کاملChiral Low-Energy Constants
The progress in determining the coupling constants of mesonic chiral Lagrangians is reviewed, with emphasis on the work performed in three successive European Networks (Eurodaphne I and II, Euridice). Reliable estimates of those constants are essential for making full use of next-to-next-to-leading-order calculations in chiral perturbation theory. The precision in the values of the strong coupl...
