Status of some P-wave baryon resonances and importance of inelastic channels

Abstract

We analyze the current status of three P-wave baryon states $N(1710){1/2}^{+}$, $N(1900){3/2}^{+}$, and $\Delta (1600){3/2}^{+}$ as given in the Review of Particles Physics (RPP). Since the evidence for a particle's existence is linked to its RPP "star" rating, we discuss its subjective present definition. We also present the accumulating evidence supporting these states and give our new "star" rating recommendations.
