Description
The study of bound states, formed by quark c and antiquark anti c (Charmonium), is a source of very important information to understand the basic theory of strong interactions. Experiment E760 at Fermilab is designed to give a precise measurement of the mass and width of the Charmonium states which cannot be formed directly in e+e- collisions. In this experiment, a non magnetic detector system, mounted inside the Antiproton source tunnel, detects the products of collisions of antiprotons, circulating inside the Accumulator vacuum pipe, with an H2 internal jet target. The excitation curve for resonance formation is obtained by changing in small steps the energy of the Antiproton beam and identifying the resonance through the detection of its electromagnetic decay products. The experiment has been running since the middle of June 1990 and, in the first two months, has collected data for an integrated luminosity of 6.4 pb-1. Scans were performed at the formation energy for Ψ, Ψ, χ1, χ2 and they have yielded precise measurements of the parameters which characterize these resonances. After a three months shut-down we will resume data taking to study singlet Charmonium states. (orig.)
