Observation of a |/S/|=1 baryon state at a mass of 1.528~GeV in
    quasi-real  photo production, *Ken Garrow*, HERMES
    Collaboration/TRIUMF/ – /The predictions for exotic baryon states
    consisting of a five quark structure have existed for some two
    decades.  Up until the past couple of years no evidence of such
    exotic baryon configurations had been observed.  Recently several
    photo production experiments and an experiment using the K^+ Xe
    reaction have reported the observation of an exotic _  baryon
    state.  In the HERMES experiment, using quasi-real photo production
    on a deuterium target, a narrow baryon state has been observed in
    the _  decay channel. The HERMES contribution to the existing
    world's data set of this exotic baryon, now referred to as the q^+ ,
    is the most accurate mass determination and the first indication of
    a finite width.
