Search for a pentaquark decaying to p K_S^0

Abstract

We present a search for a pentaquark decaying strongly to $p{K}_S^0$ in $\gamma N$ collisions at a center-of-mass energy up to 25 GeV/$c^2$. Finding no evidence for such a state in the mass range of 1470 MeV/$c^2$ to 2200 MeV/$c^2$, we set limits on the yield and on the cross section times branching ratio relative to ${\Sigma }^{\ast }(1385{)}^{\pm }$ and $K^{\ast }(892{)}^{+}$.
