Evaluation of the Axial Vector Commutator Sum Rule for Pion-Pion Scattering
Stephen L. Adler, F. J. Yndurain
We consider the sum rule proposed by one of us (SLA), obtained by taking the expectation value of an axial vector commutator in a state with one pion. The sum rule relates the pion…
Some comments on calculations of the scalar radius of the pion and the chiral constant
F. J. Yndurain
The pion scalar radius is given by , with the phase of the scalar form factor. Below threshold, , $δ…
Scattering amplitudes at multi TeV energies
F. J. Yndurain
We show that a generalized Regge behaviour, where , $α_P…
Comments on some chiral-dispersive calculations of scattering
F. J. Yndurain
We consider the scattering amplitude obtained by Colangelo, Gasser and Leutwyler (CGL), using dispersion relations and chiral perturbation theory to two loops. We point out th…
Low Energy Pion Physics
F. J. Yndurain
In these notes we present an introductory review on various topics about low energy pion physics (some kaon physics is discussed as well). Among these, we include the uses of analy…
Restriction on SUSY Masses from
M. J. Herrero, F. J. Yndurain
We remark that the precision of recent determinations of is such that one can get bounds on supersymmetric partner masses (squark and gluino) by requiring consistency…
