Abstract. In 1997 Diakonov, Petrov, and Polyakov, calculated the width of the exotic baryon that they called $\Theta^{ + }$ . The prediction, $\Gamma(\Theta^{ + })\lesssim 15$ MeV, has received considerable attention, especially in light of the narrowness of the experimentally reported $\Theta^{ + }$ resonance. However, there is an arithmetic error in their work: when corrected, the width estimate quoted in that paper should have been $\lesssim 30$ MeV.
