Finally, I have to confess to my personal skepticism about pentaquarks. Nearly two decades ago, there was a similar stampede for the existence of dibaryons, and for several years I made valiant searches for them. While claims for nearly 40 dibaryons with masses between 1900 and 2250 MeV were made, not a single one survived high resolution, high statistics measurements45. This research was supported by the U. S. Department of Energy.
