We provide a comprehensive description of experiment E835 at Fermilab, a high-precision experimental study of charmonium bound states. The ccbar states are formed in ppbar annihilations of cooled antiprotons stored in the Fermilab Antiproton Accumulator using a dense internal hydrogen gas-jet target. We describe the experimental strategies adopted for detecting the tiny ccbar resonant signals in the huge non-resonant hadronic background, and for measuring resonance parameters with high precision.

Abstract
We provide a comprehensive description of experiment E835 at Fermilab, a high-precision experimental study of charmonium bound states. The ccbar states are formed in ppbar annihilations of cooled antiprotons stored in the Fermilab Antiproton Accumulator using a dense internal hydrogen gas-jet target. We describe the experimental strategies adopted for detecting the tiny ccbar resonant signals in the huge non-resonant hadronic background, and for measuring resonance parameters with high precision.File in questo prodotto:
