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…

Searching for the Scalar Glueball
Wolfgang Ochs
Existence of gluonic resonances is among the early expectations of QCD. Today, QCD calculations predict the lightest glueball to be a scalar state with mass within a range of about…

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…
