Karliner, M., & Lipkin, H. J. (2004). Why the Theta+ is seen in some experiments and not in others: A Possible explanation..
The contradiction between evidence for and against the existence of the + pentaquark might be resolved if it only appears as a result of a particular production mechanism which is present in some experiments and absent in others. We examine the implications of + production via decay of a cryptoexotic N resonance with a mass of about 2.4 GeV corresponding to a peak in the experimental data for the invariant mass of the ( +,K−) system. Further experimental checks are suggested.
