Charge asymmetries in e+e- -> pi+ pi- gamma at the phi resonance

A. Gallegos, J. L. Lucio, G. Moreno +1

We consider the forward-backward pion charge asymmetry for the e^{+}e^{-}\toπ^{+}π^{-}γprocess. At tree level we consider bremsstrahlung and double resonance contributions. Althoug…

$π π$ Invariant mass spectrum in $V^{'} \to V π π$ and the $f_{0} (600)$ pole

A. Gallegos, J. L. Lucio M., J. Pestieau

We consider the phenomenological description of the two pion invariant mass spectrum in the $V^{'} \to V π π$ decays. We study the parametrization of the amplitude involving both $S$ a…

On the mass, width and coupling constants of the f0(980)

R. Escribano, A. Gallegos, J. L. Lucio M. +2

Using the pole approach we determine the mass and width of the $f_{0} (980)$ ; in particular, we analyze the possibility that two nearby poles are associated to it. We restrict our ana…
