The experimental search for the image in the image reaction with CLAS Original Research Article

Since the LEPS collaboration reported the first evidence for a S=+1 baryon resonance in early 2003, dubbed Θ+, twelve other experimental groups have confirmed this exotic state. At the same time, there are a number of experiments, mostly at high energies, that report null results. To find a definite answer to the question of the existence or non- existence of the Θ+ and of the other 5-quark baryons and, if they do exist, to determine their intrinsic properties, second generation experimental programs have been undertaken in different laboratories, among these at the Jefferson Laboratory (JLab). Here the status of the analysis of the γd→Θ+Λ reaction measured with the CLAS detector in the Hall B of JLab is reported.
