“…For light mesons, the Regge trajectories are suggested to be linear although the parameters take different values [78][79][80][81][82][83]. By fitting the experimental data, we find that the new Regge trajectory is better than the linear one even for π mesons, see Fig.…”

“…For small momentum transfers between the proton and the neutron (−t < 0.1 GeV 2 ), the scalar amplitudes show a dip around 1 GeV, while f 0 (980) is observed as a peak for large momentum transfers (−t > 0.4 GeV 2 ). This observation has been interpreted as evidence for a hard component in the f 0 (980) [35,899,907,1118]. However, the strong dependence of f 0 (980)-production on the momentum transfer between proton and neutron can also well be reproduced by a change of the interference between the resonance structure and the non-resonant background when and a 1 (1230) scattering are considered, and the data are fully compatible with the molecular picture of f 0 (980) [1119][1120][1121][1122].…”

“…Such analyses have the distinctive advantage that a complete meson spectrum emerges which sums the combined knowledge from very different reactions into one unified picture. A summary of results can be found in [907].…”

“…The extra state, which was found and investigated in [5,6,8], namely, f bare 0 (1580), should be identified as a scalar glueball, for its decay couplings satisfy the requirements inherent in the gluonium, see discussion in [3]. So, …”
