Why the Theta+ is seen in some experiments and not in others - a possible explanation | | Marek Karliner

3 May 2004 | | Journal: | Phys.Lett. B597 (2004) 309-313 | | Subject: | hep-ph hep-ex | | Abstract: | The contradiction between evidence for and against the existence of the Theta+ 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 Theta+ 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 (Theta+,K-) system. Further experimental checks are suggested. | | Source: | arXiv, hep-ph/0405002 | | Services: | Forum | Review | PDF | Favorites | |
