Title: Update on the Pentaquark Search
Abstract: The pentaquark known as the Theta+ has now been seen in over ten experiments worldwide, although the statistics of each measurement is limited. In addition, there are some null results that do not show any hint of a Theta+ peak, and the explanation is not clear. Hence we must be a bit cautious about the existence of the Theta+. In this talk, the evidence for the Theta+ is examined, with focus given to the strongest experiments. Also, new unpublished results on a possible new narrow N* state, which could be identified with the next level in the anti-decuplet group, will be reviewed. Finally, portions of the new CLAS data on deuterium with high-statistics will be shown.
