&+circ; Search with Quasi-Free Photoproduction in Deuterium
Abstract
The production of a possible exotic S=1 pentaquark off a neutron is being investigated in CLAS at Jefferson Lab. Using a tagged photon beam of energy up to 3.6 GeV incident on a 24 cm liquid deuterium target, the final state pK^0sK^-(p) is produced and identified by reconstructing the K^0s from ^+^- and spectator proton in missing mass. Evidence for the photoproduction of ^+K^- and ^+->pK^0s is investigated, and a comprehensive description of the current status of the analysis will be presented, including cuts, corrections, and backgrounds.
