Interpretation of the Theta+ as an isotensor pentaquark with weakly decaying partners
Description
The Θ+(1540), recently observed at LEPS, DIANA and CLAS, is hypothesized to be an isotensor resonance. This implies the existence of a multiplet where the Θ++, Θ+ and Θ0 have isospin-violating strong decays, and the Θ+++ and Θ- have weak decays and so are long-lived. Production mechanisms for these states are discussed. The JP assignment of the Θ is most likely 1/2- or 3/2- or 5/2-
