Title: Search for Pentaquarks: the Experimental Program at CLAS

Abstract

Experimental evidences for the existence of exotic 5-quark baryons have been reported recently by several groups. These data may open new perspectives in hadron spectroscopy as well as in QCD. However, the statistical significance of these results is quite low, and the pentaquark signal has not been seen in various other experiments. The new dedicated experiments currently underway at CLAS will hopefully give a clearer answer on the existence and, possibly, on the properties of pentaquarks. This paper summarizes the results obtained so far in the search for 5-quark states and describes the characteristics and goals of the new experiments running at CLAS.
