Quark mass dependence of the rho and sigma from dispersion relations and Chiral Perturbation Theory
C. Hanhart, J. R. Pelaez, G. Rios
We use the one-loop Chiral Perturbation Theory pion-pion scattering amplitude and dispersion theory in the form of the inverse amplitude method, to study the quark mass dependence…
Chiral Extrapolation of light resonances from Unitarized Chiral Perturbation Theory
J. R. Pelaez, C. Hanhart, G. Rios
Both scalar and vector light resonances can be generated from the unitarization of one-loop chiral perturbation theory. This amounts to using in a dispersion relation the chiral ex…
The Inverse Amplitude Method and Adler Zeros
A. Gomez Nicola, J. R. Pelaez, G. Rios
The Inverse Amplitude Method is a powerful unitarization technique to enlarge the energy applicability region of Effective Lagrangians. It has been widely used to describe resonanc…
Scalar mesons from Unitarized Chiral Perturbation Theory: N_c and quark mass dependences
J. R. Peláez, G. Ríos
We review recent studies of light scalar meson properties by means of unitarization techniques, obtained from dispersion theory, and applied to the Chiral Perturbation Theory expan…
