Study of low-mass peripheral states in a small triggered bubble chamber

PDF Version Also Available for Download.

Description

The authors propose to study {approx} 40,000 events of the type beam particle + proton {yields} M + beam particle where M is a fairly low mass (2-5 GeV) state which is peripherally produced and slow in the lab. The decay products of M would be studied in detail as a function of M at two different beam momenta. The choice of beam particle and the two beam momenta would depend on what was technically most feasible, but at least the beam momenta should be greater than 100 GeV/c. A hydrogen bubble changer, pulsing several times per machine cycle, would ... continued below

Description

The authors propose to study {approx} 40,000 events of the type beam particle + proton {yields} M + beam particle where M is a fairly low mass (2-5 GeV) state which is peripherally produced and slow in the lab. The decay products of M would be studied in detail as a function of M at two different beam momenta. The choice of beam particle and the two beam momenta would depend on what was technically most feasible, but at least the beam momenta should be greater than 100 GeV/c. A hydrogen bubble changer, pulsing several times per machine cycle, would be triggered on a fast forward particle near the beam momentum. The invariant mass M would be calculated for each event by momentum analysis of this particle. The experiment requires a beam with a momentum resolution {Delta}p/p of .002 or better and an emittance of .1 mm - mrad.
