Influence of Vector Mesons on the f0(600) Decay Width in a Linear Sigma Model with Global Chiral Invariance

Denis Parganlija, Francesco Giacosa, Dirk H. Rischke

We consider a globally invariant chiral Lagrangian that contains vector and axial-vector mesons. We compute the f0(600) decay width into two pions and pion-pion scattering lengths…
