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…

A rational approximation to <VV-AA> and its O(p^6) low-energy constant
P. Masjuan, S. Peris
Using a sequence of rational approximants and the large-Nc limit of QCD, we estimate the value of the low-energy constant C_87 which appears in the Lagrangian of Chiral Perturbatio…
