I (J P ) = 21 ( 23 − ) Status:

N(2120) 3/2−∗∗∗Before the 2012 Review, all the evidence for a J P = 3/2− statewith a mass above 1800 MeV was filed under a two-star N(2080).
There is now evidence from ANISOVICH 12A for two 3/2− statesin this region, so we have split the older data (according to mass)
between a three-star N(1875) and a two-star N(2120).
