Experimental medium energy physics. Annual progress report, June 1983-May 1984
During the past year the principal activities of the C-MU Medium Energy Physics Group have included running of previously approved experiments, the development of hardware and software for new experiments, continued analysis of previously accumulated data, and the development of model calculations to be compared with these data. Major data runs have taken place on a hypernuclear experiment (AGS 781) at the AGS, and on an antiproton run at CERN/LEAR (PS-185). In addition, planning is continuing for further hypernuclear lifetime measurements in /sup 4/ /sup 5/He, and for a possible search for the H-particle. For these experiments extensive hardware and software development has taken place, requiring much of the group's effort. In our ongoing studies of the pion annihilation mechanism, the emphasis has shifted from two-body processes to those involving three-body final states. A large effort is being devoted to the analysis of our (..pi..,xy) data accumulated at LAMPF on targets of /sup 6/ /sup 7/Li, /sup 14/N, /sup 16/O and CD/sub 2/. During the year considerable effort was devoted to Monte Carlo simulations of the rare weak decay K/sup +/ ..-->.. ..pi../sup +/ nu anti nu; this experiment has been approved as AGS 787. In addition, work has continued on the development of model calculations of the (..pi..,pp) and anti pp ..-->.. anti ..lambda lambda.. reactions. (WHK)
