Abstract: (IOP)

BNL E910 has measured strange baryon production as a function of collision centrality for 17.5 GeV c -1 p-Au collisions. Collision centrality is defined by nu, the mean number of projectile-nucleon interactions estimated from the `grey' track multiplicity. The measured Lambda yield increases faster than the participant scaling expectation for GRAPHIC and then saturates. A simple parametrization of this dependence applied to nucleus-nucleus collisions reproduces the measured E866 kaon and WA97 Lambda centrality-dependent yields. The increase in Lambda production to GRAPHIC is also evident for Lambdas which are leading baryons, in disagreement with predictions from RQMD.
