Unitarized U(3) CHPT. Meson-meson scattering. Scalar resonances.

Jose A. Oller (Murcia)

We report on a recent work where meson-meson scattering is
calculated in U(3) CHPT at the one-loop level. The resulting amplitudes
are then unitarized in coupled channels following Unitary CHPT. A good
agreement with experimental data in the S- and P-waves are obtained up
to energies around 1.4 GeV.  The related spectroscopy is studied and
special attention is given to the scalar resonances. The dependence of
their poles on Nc will be discussed.
