Pentaquark searches
Abstract
Current evidence does not favor the existence of the \thplus pentaquark, which was reported by several groups in the years after 2002. The question naturally arises: how could many groups could have seen fluctuations in their data at the level of 35 $\sigma$ statistical significance? An example of a statistical fluctuation is given and the number of $\sigma$'s necessary for claims of discovery are examined. Using this guideline, a possible answer to the above question is presented.
