Model Selection in Partial-Wave Decomposition — •Karl Bicker, Suh-Urk Chung, Oliver Drotleff, Jan Friedrich, Boris Grube, Fabian Krinner, Stephan Paul, Dimitry Ryabchikov, and Sebastian Uhl — Physik Department, E18, Technische Universität München

Model selection in the context of partial-wave decomposition of data from diffractive dissociation reactions is a daunting task. Due to the large number of possible waves which are conceivable to contribute to the measured distributions, an almost infinite number of models can be constructed. We will present a method which uses a maximum-likelihood estimation together with a prior function to select an appropriate set of partial waves that describes the data at hand.
