Regge-plus-resonance predictions for charged-kaon photoproduction from the deuteron
Pieter Vancraeyveld, Lesley De Cruz, Jan Ryckebusch +1
We present a Regge-inspired effective-Lagrangian framework for charged-kaon photoproduction from the deuteron. Quasi-free kaon production is investigated using the Regge-plus-reson…
Regge-model predictions for K+Sigma photoproduction from the nucleon
Pieter Vancraeyveld, Lesley De Cruz, Jan Ryckebusch +1
We present Regge-model predictions for the p(gamma,K+)Sigma0 and n(gamma,K+)Sigma- differential cross sections and photon-beam asymmetries in the resonance region. The reaction amp…
Helicity amplitudes and electromagnetic decays of strange baryon resonances
Tim Van Cauteren, Jan Ryckebusch, Bernard C. Metsch +1
We present results for the helicity amplitudes of the lowest-lying hyperon resonances Y*, computed within the framework of the Bonn constituent-quark model, which is based on the B…
Electromagnetic form factors of hyperons in a relativistic quark model
T. Van Cauteren, T. Corthals, S. Janssen +4
The relativistically covariant constituent quark model developed by the Bonn group is used to compute the EM form factors of strange baryons. We present form-factor results for the…
Sigma photoproduction in the resonance region
S. Janssen, J. Ryckebusch, D. Debruyne +1
A study of p(gamma,K)Sigma processes in an isobar model at tree level is reported. By comparing model calculations to the published SAPHIR data, we explore the possible role of dif…
Bridging Two Ways of Describing Final-State Interactions in A(e,e'p) Reactions
D. Debruyne, J. Ryckebusch, S. Janssen +1
We outline a relativistic and unfactorized framework to treat the final-state interactions in quasi-elastic A(e,e'p) reactions for four-momentum transfers Q (GeV/…
Kaon photoproduction: background contributions, form factors and missing resonances
S. Janssen, J. Ryckebusch, D. Debruyne +1
The photoproduction p(gamma, K+)Lambda process is studied within a field-theoretic approach. It is shown that the background contributions constitute an important part of the react…
The role of hyperon resonances in p(gamma,K+)Lambda processes
S. Janssen, J. Ryckebusch, W. Van Nespen +2
We discuss the role of hyperon resonances in the u-channel when modeling p (gamma,K+)Lambda processes in an effective Lagrangian approach. Without the introduction of hyperon reson…
