Effective Field Theory Description of the Pion Form Factor *

چکیده
Using our present knowledge on effective hadronic theories, short–distance QCD information, the 1/N C expansion, analyticity and unitarity, we derive an expression for the pion form factor, in terms of m π , m K , M ρ and f π. This parameter–free prediction provides a surprisingly good description of the experimental data up to energies of the order of 1 GeV.

When Is It Possible to Use Perturbation Technique in Field Theory ?
The vector pion form factor is used as an example to analyze this question. Given the experimental radius of the pion, the crucial question is whether perturbative methods could be used for the effective chiral lagrangian to calculate the pion form factor. Our analysis shows that the pion rms radius is far too large (or the related ρ resonant mass is too low) for the perturbation theory to be v...
متن کاملHadronic light - by - light scattering contribution to the muon g − 2 ∗
We briefly review the current status of the hadronic light-by-light scattering correction to the muon g−2. Then we present our semi-analytical evaluation of the pion-pole contribution, using a description of the pion-photonphoton form factor based on large-NC and short-distance properties of QCD. We also sketch an effective field theory approach to hadronic light-by-light scattering. In view of...

We describe the pion electroproduction processes in the ∆(1232)-resonance region within the framework of chiral effective-field theory. By studying the observables of pion electroproduction in a next-to-leading order calculation we are able to make predictions and draw conclusions on the properties of the N → ∆ electromagnetic form factors.
متن کاملConvergence Issues in Nucleon-nucleon Effective Field Theory
The origin of the breakdown scale in an effective field theory treatment of nuclear forces is investigated. Different organizational schemes used in the nonperturbative calculation of nucleon-nucleon scattering seem to break down for different physical reasons. It is argued that the same physics is actually responsible, namely strong two-pion exchange as also observed in the pion scalar form fa...
متن کاملNucleon-Nucleon Effective Field Theory Without Pions
Nuclear processes involving momenta much below the mass of the pion may be described by an effective field theory in which the pions do not appear as explicit degrees of freedom. The effects of the pion and all other virtual hadrons are reproduced by the coefficients of gauge-invariant local operators involving the nucleon field. Nucleon-nucleon scattering phase shift data constrains many of th...
