An experimental program in strong and electromagnetic interaction physics of elementary particles is being carried out using three hybrid bubble chamber systems. Experiments are being performed utilizing the accelerators of the laboratories at Batavia, Stanford, and Geneva, Switzerland. The bubble chamber - hybrid system group is engaged in several experiments at the Fermilab. Extensive analysis of multiparticle production in ..pi../sup -/p interactions at 147 GeV/c was carried out, with particular emphasis this year on a comparison of data with electroproduction data of hadrons with high-P/sub T/ and with the Field and Feynman quark-quark scattering model. Preliminary results have also been presented on an investigation of ..pi../sup +/p, K/sup +/p, and pp interactions at the same momentum; and this work is continuing. Two much higher statistics experiments will start later in 1980 at FNAL to study ..pi../sup + -/, K/sup +/, and p/sup + -/ interactions in hydrogen, and in aluminum, silver, and gold foils, at beam momenta of 200 and 400 GeV/c. A similar study of ..pi../sup +/p, K/sup +/p, and pp interactions at 250 to 300 GeV/c using the large European Hybrid System at CERN will also be started. In addition, we shall begin an experiment on charm and vector meson photoproduction in a polarized monoenergetic backscattered laser beam of 20 GeV using the SLAC Hybrid Facility. A list of publications is included.
