The Amplitude in Generalized Chiral Perturbation Theory
M. Knecht, B. Moussallam, J. Stern
The interaction is studied at one loop order in the framework of Generalized Chiral Perturbation theory
Generalized Chiral Perturbation Theory
M. Knecht, J. Stern
The Generalized Chiral Perturbation Theory enlarges the framework of the standard PT, relaxing certain assumptions which do not necessarily follow from QCD or from experiment, a…
On the Pais--Treiman method to measure phase shifts in decays
G. Colangelo, M. Knecht, J. Stern
We evaluate theoretical uncertainties to the method of Pais and Treiman to measure the phase shifts in decays. We find that they are very small, below .
Chiral Symmetry Aspects of the Scalars
B. Moussallam, J. Stern
Electromagnetic decays of the scalar mesons are shown to be constrained by chiral symmetry as a consequence of the fact that, in the chiral limit, the two and three-point functions…
The Reaction in Generalized Chiral Perturbation Theory
M. Knecht, B. Moussallam, J. Stern
The cross section for and the pion polarizabilities are computed, within generalized chiral perturbation theory, in the full one loop approximation, {\it i.e.} up to…
