Progress report of a research program in experimental high energy physics, 1 January-31 December 1984
An experimental program to study the interactions of hadrons, photons, and neutrinos is being carried out using hybrid systems which include bubble chambers as visible targets and counter spectrometers for particle detection, identification, and momentum measurements. Experiments have been run in both positive and negative hadron beams at Fermilab, and with polarized photons at SLAC. Experiments with neutrino beams at Tevatron II at Fermilab are in preparation. We have been analyzing the film and counter data of our one-million-picture exposure for the study of ..pi..+-, K/sup +/ and p interations in hydrogen and magnesium, silver and gold, at a beam momentum of 200 GeV/c, as well as continuing the physics analysis of our earlier FNAL experiments on ..pi../sup +/p, K/sup +/ p, and pp interactions at 147 GeV/c. During the past year analysis has continued on the data of SLAC experiments studying the interactions in hydrogen of 20 GeV polarized photons. Results have been obtained on photoproduction of charm and on the lifetimes of charmed particles, and on vector meson and strange particle production. Inclusive ..gamma..p interactions are being studied in detail in this high statistics sample. Another experiment, was run at 10.5 GeV, to search for evidence of a predicted threshold enhancement in the charm photoproduction cross section. Preparations are in progress for neutrino interaction studies at Tevatron II. An experiment will run starting early in 1985 in the wide band neutrino beam with hybrid system designed for the tau neutrino search to be run with the beam dump.
