Minimal complete sets for two pseudoscalar meson photoproduction
Philipp Kroenert, Yannick Wunderlich, Farah Afzal +1
For photoproduction reactions with final states consisting of two pseudoscalar mesons and a spin-1/2 baryon, 8 complex amplitudes need to be determined uniquely. A modified version…
Mathematical aspects of phase rotation ambiguities in partial wave analyses
Yannick Wunderlich
The observables in a single-channel -body scattering problem remain invariant once the amplitude is multiplied by an overall energy- and angle-dependent phase. This invariance i…
Complete experiments in pseudoscalar meson photoproduction
Yannick Wunderlich
The problem of extracting photoproduction amplitudes uniquely from so called complete experiments is discussed. This problem can be considered either for the extraction of full pro…
Amplitude- and truncated partial-wave analyses combined: A novel, almost theory-independent single-channel method for extracting photoproduction multipoles directly from measured data
A. Švarc, Y. Wunderlich, L. Tiator
Amplitude- and truncated partial-wave analyses are combined into a single procedure and a novel, almost theory-independent single-channel method for extracting multipoles directly…
The complete experiment problem of pseudoscalar meson photoproduction in a truncated partial wave analysis
Yannick Wunderlich
This dissertation treats the problem of complete experiments for pseudoscalar meson photoproduction, in the context of a truncated partial-wave analysis (TPWA). The work contains a…
Moravcsik's theorem on complete sets of polarization observables reexamined
Y. Wunderlich, P. Kroenert, F. Afzal +1
We revisit Moravcsik's theorem on the unique extraction of amplitudes from polarization observables, which has been originally published in 1985. The proof is (re-) written in a mo…
