Vector Meson Dominance as a first step in a systematic approximation: the pion vector form factor
P. Masjuan, S. Peris, J. J. Sanz-Cillero
Pade Approximants can be used to go beyond Vector Meson Dominance in a systematic approximation. We illustrate this fact with the case of the pion vector form factor and extract va…
Some Remarks on the Pade Unitarization of Low-Energy Amplitudes
Pere Masjuan, Juan Jose Sanz-Cillero, Javier Virto
We present a critical analysis of Pade-based methods for the unitarization of low energy amplitudes. We show that the use of certain Pade Approximants to describe the resonance reg…
Studies on phase motion in the process
Z. X. Zhang, J. J. Sanz-Cillero, X. Y. Shen +3
We propose a measurement on the elastic scattering phase shift difference through process in future high statistics BES-III experiment. The de…
Can a resonance theory be a renormalizable theory?
J. J. Sanz-Cillero
In this talk we make an exhaustive analysis of the possible chiral invariant operators that may described the resonance decay S->pi pi. These provide at the same time the only avai…
Renormalizable Sectors in Resonance Chiral Theory: S -> pi pi Decay Amplitude
L. Y. Xiao, J. J. Sanz-Cillero
We develop a resonance chiral theory without any a priori limitation on the number of derivatives in the hadronic operators. Through an exhaustive analysis of the resonance lagrang…
On the structure of two-point Green-functions at next-to-leading order in 1/Nc
J. J. Sanz-Cillero
The structure of the two-point QCD Green-functions is studied in this note in the limit of large number of colours. Their general form at next-to-leading order in 1/Nc is derived k…
