Effective Field Theory Description of the Pion Form Factor *
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.
متن کاملThe Pion Form Factor
The pion, and specifically its charge form factor, is of key interest in the study of the quark-gluon structure of hadrons. This is exemplified by the many calculations that treat the pion as one of their prime examples. One of the reasons is that the valence structure of the pion, being 〈qq̄〉, is relatively simple. Hence it is expected that the value of the four-momentum transfer squared Q, dow...
متن کاملEffective Field Theory of the Pion-nucleon-interaction *
In the first part of the talk, I discussed the nature of the effective theory that describes the properties of the pion-nucleon-interaction at low energies, using the static model as a starting point. In the second part, I then pointed out that the infrared singularities occurring in the πN scattering amplitude are stronger and of a more complex structure than those encountered in ππ scattering...
متن کاملThe Pion – Nucleon Interaction as an Effective Field Theory
After a brief survey of effective field theories, the linear σ model is discussed as a prototype of an effective field theory of the standard model below the chiral–symmetry–breaking scale. Although it can serve as a toy model for the pion–nucleon interaction, the linear σ model is not a realistic alternative to chiral perturbation theory. The heavy–baryon approach to chiral perturbation theory...
متن کاملQuark structure of the pion and pion form factor.
We consider the pion structure in the region of low and moderately high momentum transfers: at low Q 2 , the pion is treated as a composite system of constituent quarks; at moderately high momentum transfers, Q 2 = 10 ÷ 25 GeV 2 , the pion form factor is calculated within perturbative QCD taking into account one–gluon hard exchange. Using the data on pion form factor at Q 2 < 3 GeV 2 and pion a...
