Baryon spectroscopy: new results and perspectives
Argonne Physics Division Seminar - 15 Dec 2014
3:30 PM, Building 203, Conference Room R-150

First results from the Frozen Spin Target (FroST) at Jefferson Lab are a significant step towards the understanding of the spectrum of excited baryons. Double polarization observables at an unprecedented precision put tight constraints on the amplitude as will be discussed. Conclusive answers in baryon spectroscopy are a long-sought goal. Necessary steps towards this goal will be discussed, such as statistical criteria, the need for hadron beams, and the need for a suitable amplitude parameterization to make the connection to ab-initio QCD approaches.
