Semi-inclusive {Lambda} and K{sub S} Production in p -Au Collisions at 17.5 GeV/c

The first detailed measurements of the centrality dependence of strangeness production in p-A collisions are presented. {Lambda} and K{sub S} dn/dy distributions from 17.5GeV/c p-Au collisions are shown as a function of ''grey'' track multiplicity and the estimated number of coll...

Description
Summary:The first detailed measurements of the centrality dependence of strangeness production in p-A collisions are presented. {Lambda} and K{sub S} dn/dy distributions from 17.5GeV/c p-Au collisions are shown as a function of ''grey'' track multiplicity and the estimated number of collisions, {nu} , made by the proton. The {nu} dependence of the {Lambda} yield deviates from a scaling of p-p data by the number of participants, increasing faster than this scaling for {nu}{
