11 Sep 2003 | Journal: | Phys.Atom.Nucl. 67 (2004) 682-687; Yad.Fiz. 67 (2004) 704-709 | Subject: | hep-ex | Abstract: | A narrow baryon resonance is observed in invariant mass of the pKshort system formed in neutrino and antineutrino collisions with nuclei. The mass of the resonance is estimated as (1533+-5)MeV. The observed width is less than 20 MeV, and is compatible with being entirely due to experimental resolution. The statistical significance of the signal is near 6.7 standard deviations. As the position of the observed resonance does not match the mass of any known Sigma^{*+} state, we believe that it arises from neutrino production of the Theta^+ pentaquark baryon. The analysis is based on the data obtained in past neutrino experiments with big bubble chambers: WA21, WA25, WA59, E180 and E632. | Source: | arXiv, hep-ex/0309042 | Services: | Forum | Review | PDF | Favorites |
