Nucleon-antinucleon annihilation at LEAR
Claude Amsler
This report is a historical review of the salient results in low energy antiproton-proton and antineutron-proton annihilation obtained at the Low Energy Antiproton Ring (LEAR), whi…
Further evidence for a large glue component in the f0(1500) meson
Claude Amsler
We argue that the experimental decay rates of the f0(1500) meson into two pseudoscalar mesons and into two photons are incompatible with a quark-antiquark state and that the f0(171…
Is a Scalar Glueball?
Claude Amsler, Frank Close
Following the discovery of two new scalar mesons, and at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are inco…
EVIDENCE FOR A SCALAR GLUEBALL
Claude Amsler, Frank Close
We show that the newly discovered scalar meson at LEAR has properties compatible with the lightest scalar glueball predicted by lattice QCD and incompatible with a $\qq…
