A truncated partial wave analysis using bayesian inference — •Jean Noël for the CBELSA/TAPS collaboration — HISKP, Rheinische Friedrich-Wilhelms Universität Bonn.

Following the description of the Standard Model of particle physics, more specifically quantum chromodynamics (QCD), so called hadrons are bound states of quarks and gluons. A difficulty in investigating these fundamental particles arises from being unable to observe them in isolation due to confinement.

One approach for investigating the formation of hadrons is the photoproduction of mesons.
The focus will lie on the reaction p + γ → p + π⁰. By employing a truncated partial wave analysis (TPWA) the approach can be kept model independent. A fully bayesian investigation will be employed and the advantages of extracting the partial waves (up to an overall phase) with this method will be discussed.

Preliminary results obtained from this approach will be shown.
