Abstract

We analyze the current status of three P-wave baryon states N(1710)1/ 2⁺, N(1900)3/2⁺, and Δ(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.
