Two-photon width and gluonic component of sigma/f_0(600)
G. Mennessier, S. Narison, W. Ochs
We analyse data on pi pi and gamma gamma scattering below 700 MeV within an improved analytic K-matrix model. This model is based on an effective theory with couplings between reso…

Glueball nature of the sigma/f_0(600) from pi-pi and gamma-gamma scatterings
G. Mennessier, S. Narison, W. Ochs
We estimate the I=0 scalar meson sigma/f_0(600) parameters from pi-pi and gamma-gamma scattering data below 700 MeV using an improved analytic K-matrix model. A fit of the hadronic…

Can the gamma-gamma processes reveal the nature of the sigma ?
G. Mennessier, P. Minkowski, S. Narison +1
We reanalyse the gamma-gamma scattering data and conclude that in the mass region below 1 GeV the cross section for gamma-gamma to pi^0-pi^0 can be largely explained by the one pio…
