High energy physics studies of particle interactions and the search for new particles. Annual progress report, May 15, 1978--May 14, 1979. [Summaries of research activities at Washington University]
Continued effort was directed to the study of multiparticle production processes in nuclei. In the earlier phases of this contract, protons were used as the projectile; within the last two years we have begun to investigate cascades produced by projectiles having quite different mean-free-paths in nuclear matter. In the past year, three papers were published summarizing results on multiparticle production on nuclei using hadron and lepton beams. A new experiment was performed at Fermilab to search for new particles produced by neutrino interactions in nucelar emulsion targets located inside the 15' bubble chamber. In this hybrid experiment, the deuterium filled bubble chamber provides a rough location for the interaction vertex, and identifies and momentum analyzes the produced particles while the emulsion provides a close look at the event vertex. The experiment is a collaborative effort involving U.S., Polish and Soviet groups. Russian-made cryogenically sensitized emulsions will be used. As a result of participation in the hybrid emulsion-bubble chamber experiment as well as the earlier muon, pion and proton experiments, at disposal is a unique opportunity to compare and contrast leptoproduction and hadroproduction. Also continued is an analysis of nucleus-nucleus interactions from LBL heavy ion beams. A list of publications is included.
