Strong interaction experiments at the ZGS

The history of two related strong interaction experiments carried out at the Argonne ZGS accelerator in the mid 1960’s is described. These experiments involved the study of the production and decay distributions of π+p→ρ+N for forward production of ρ, and π+p→N∗+π for backward production of N∗. Special emphasis is given to the role played by Kent Terwilliger in conceiving these experiments and bringing them to a successful conclusion. A literature search is carried out to assess the impact of these experiments on the strong interaction physics of the period.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87538/2/125_1.pd
