How Universal is the Coupling in the Sigma Model?

Denis Parganlija, Francesco Giacosa, Dirk H. Rischke

We calculate pion-pion scattering lengths and sigma, rho and a1 decay widths from a gauged linear sigma model with two flavours and its globally invariant generalisation.

Radiative $ϕ$ decays with derivative interactions

Francesco Giacosa, Giuseppe Pagliara

We study the line shapes of radiative $ϕ$ -decays involving virtual $f_{0} (980)$ and $a_{0} (980)$ mesons which decay, via derivative couplings, to $π^{0} π^{0}$ and $π^{0} η$ respecti…
