In 1997 Diakonov, Petrov, and Polyakov, calculated the width of the exotic baryon that they called . The prediction, MeV, has received considerable attention, especially in light of the narrowness of the experimentally reported resonance. However, there is an arithmetic error in their work: when corrected, the width estimate quoted in that paper should have been MeV.
