Search for a new baryonic state decaying to $pK^0_S$
  We report on a new ZEUS search for a narrow state decaying into $p(\bar{p})K^0_S$, which was previously claimed by the ZEUS collaboration. In the present search, which uses much increased statistics, no evidence for this state is found. Limits on the cross section for such a state are given.
