Pentaquark Search with Quasi-Free Photoproduction in Deuterium
Abstract
Photoproduction of a possible exotic S=+1 pentaquark off a neutron is being investigated in CLAS at Jefferson Lab. A tagged photon beam of energy 1.4-3.6 GeV, produced with bremsstrahlung radiation of a 3.779 GeV electron beam, was incident on a 24 cm liquid deuterium target. The final state pK^-π ^+π ^-(p), with the spectator proton identified via missing mass, is being analyzed for a θ^+ in the pK^0s (K^0_s->π ^+π ^-) channel. A comprehensive description of the current analysis will be presented, including cuts, corrections, and backgrounds.
