Description

In this talk, I'll review the status of the eta-pi and eta'-pi final in hadroproduction (from the COMPASS collaboration) and in photoproduction (from the GlueX collaboration). We'll discuss the extraction of the resonances properties in their P and D waves (respectively the Pi_1 and A_2 resonances) and how to constraint these extractions using the high mass region (aka the double Regge region) and the finite energy sum rules.
