An alternative explanation of the dibaryon suggested by experiments at the WASA facility at the FZ Julich Cooler synchrotron

Abstract

A series of publications of the WASA collaboration culminates in a recent paper of Pricking, Bashkanov and Clement [1] claiming a dibaryon resonance at 2370 MeV. However, as explained here, there are logical flaws in this result. A natural alternative arises from the reaction pd -> N N*(1440)p_s where p_s is a spectator proton. There is supporting evidence from a recent experiment of Mielke et al. on dp -> 3He-piplus-piminus

arXiv comment5 pages, 1 figure. This is a revised version which makes use of supporting evidence from the recent experiment of Mielke et al. Conclusions remain unchanged
