Experimental medium energy physics. Annual progress report, June 1985-May 1986
During the past year the CMU Medium Energy Physics Group has been involved in the running of three experiments. In addition, software and hardware for two new experiments scheduled to take place over the next few months have been developed. A new proposal, ''Search for a Strangeness -2 Dibaryon Using a /sup 3/He Target,'' was submitted to the Brookhaven Program Advisory Committee and recently approved. In the spring of this year, studies of hypernuclear decay shifted to few body systems. Data on the decay of /sup 5//sub ..lambda../He was taken along with preliminary data on /sup 4//sub ..lambda../He. This was followed a month later by a run at LEAR to study anti ..lambda lambda.. production. The high statistics runs should allow extraction of the spin correlation coefficients not previously obtainable and also includes a detailed study at threshold. In December, a second run at LEAR began the start of anti ..lambda sigma.. production studies and tested the ability to measure K/sub s/K/sub s/ production; this channel will be used to search for the xi(2230) in the summer of 1986. In preparation for the xi(2230) search, extensive Monte Carlo simulations have been performed at CMU to aid in the design of the detector system. Data analysis routines from hyperon production studies were modified and the first K/sub s/K/sub s/ event was extracted from existing data. The CMU group has had extensive involvement in an experiment to search for strangeness production relativistic heavy ion collisions. Hardware to provide the online analysis and data storage facilities for the experiment has been purchased and developed. CMU personnel has also worked on the development of software with the flexibility required to monitor this complex experiment. 37 refs., 53 figs., 8 tabs.
