Model discrimination in pseudoscalar-meson photoproduction
J. Nys, J. Ryckebusch, D. G. Ireland +1
To learn about a physical system of interest, experimental results must be able to discriminate among models. We introduce a geometrical measure to quantify the distance between mo…
Amplitude extraction in pseudoscalar-meson photoproduction: towards a situation of complete information
Jannes Nys, Tom Vrancx, Jan Ryckebusch
A complete set for pseudoscalar-meson photoproduction is a minimum set of observables from which one can determine the underlying reaction amplitudes unambiguously. The complete se…
electroproduction above the resonance region
Tom Vrancx, Jan Ryckebusch, Jannes Nys
Background: In and electroproduction, conventional models cannot satisfactory explain the data above the resonance region, in particular the transverse cross section.…
Complete sets of observables in pseudoscalar-meson photoproduction
Tom Vrancx, Jan Ryckebusch, Jannes Nys
Pseudoscalar-meson photoproduction is characterized by four complex reaction amplitudes. A complete set is a minimum theoretical set of observables that allow to determine these am…
Charged pion electroproduction above the resonance region
Tom Vrancx, Jan Ryckebusch
[Background] Above the nucleon resonance region, the data cannot be explained by conventional hadronic models. For example, the observed magnitude of the transvers…
Incompleteness of complete kaon photoproduction
Jan Ryckebusch, Tom Vrancx
A possible roadmap for reaching a status of complete information in is outlined.
The incompleteness of complete pseudoscalar-meson photoproduction
Tom Vrancx, Jan Ryckebusch, Tom Van Cuyck +1
[Background] A complete set is a minimum set of observables which allows one to determine the underlying reaction amplitudes unambiguously. Pseudoscalar-meson photoproduction from…
Bayesian inference of the resonance content of p(gamma,K+)Lambda
Pieter Vancraeyveld, Lesley De Cruz, Jan Ryckebusch +1
A Bayesian analysis of the world's p(gamma,K+)Lambda data is presented. We adopt a Regge-plus-resonance framework featuring consistent couplings for nucleon resonances up to spin J…
Kaon photoproduction from the deuteron in a Regge-plus-resonance approach
Pieter Vancraeyveld, Lesley De Cruz, Jan Ryckebusch +1
We present a Regge-inspired effective-Lagrangian framework for kaon photoproduction from the deuteron. Quasi-free kaon production is investigated using the Regge-plus-resonance (RP…
A Bayesian analysis of kaon photoproduction with the Regge-plus-resonance model
Lesley De Cruz, Jan Ryckebusch, Tom Vrancx +1
We address the issue of unbiased model selection and propose a methodology based on Bayesian inference to extract physical information from kaon photoproduction data. W…
Bayesian inference of the resonance content of p(gamma,K^+)Lambda
Lesley De Cruz, Tom Vrancx, Pieter Vancraeyveld +1
A Bayesian analysis of the world's p(gamma,K^+)Lambda data is presented. From the proposed selection of 11 resonances, we find that the following nucleon resonances have the highes…
Consistent interactions for high-spin baryons
Tom Vrancx, Lesley De Cruz, Jan Ryckebusch +1
Consistent interactions for off-shell fermion fields of arbitrary spin are constructed from the gauge-invariance requirement of the interaction Lagrangians. These interactions play…
The Regge-plus-resonance model for kaon production on the proton and the neutron
J. Ryckebusch, L. De Cruz, P. Vancraeyveld +1
The Regge-plus-resonance (RPR) framework for kaon photoproduction on the proton and the neutron is an economical single-channel model with very few parameters. Not only does the RP…
Consistent interactions for high-spin fermion fields
Tom Vrancx, Lesley De Cruz, Jan Ryckebusch +1
We address the issue of consistent interactions for off-shell fermion fields of arbitrary spin. These interactions play a crucial role in the quantum hadrodynamical description of…
