Minimal complete sets for two pseudoscalar meson photoproduction


  • Mr. Philipp KROENERT

Primary authors



A modified version of Moravcsik’s theorem, based on graph theory, is applied to unambiguously determine the eight complex spin amplitudes for the photoproduction reaction of two pseudoscalar mesons. The intermediate result are slightly overcomplete sets of polarisation observables. In a subsequent step, these are reduced to minimal complete sets, consisting of 16 observables. As a final result, multiple minimal complete sets without any remaining ambiguities are presented for the first time.
