Gauge-invariant meson photoproduction with extended nucleons
H. Haberzettl, C. Bennhold, T. Mart +1
The general gauge-invariant photoproduction formalism given by Haberzettl is applied to kaon photoproduction off the nucleon at the tree level, with form factors describing composi…
Alternative evaluations of halos in nuclei
S. Karataglidis, P. J. Dortmans, K. Amos +1
Data for the scattering of 6He, 8He, 9Li, and 11Li from hydrogen are analyzed within a fully microscopic folding model of proton-nucleus scattering. Current data suggest that of th…
The weak strangeness production reaction in a one-boson-exchange model
A. Parreño, A. Ramos, N. G. Kelkar +1
The weak production of Lambdas in nucleon-nucleon scattering is studied in a meson-exchange framework. The weak transition operator for the reaction is identical to a…
The reaction within a one-meson-exchange model
A. Parreño, A. Ramos, N. G. Kelkar +1
With the advent of high precision proton accelerators, such as COSY in Jülich, or with medium energy accelerators like RCNP at Osaka, it may become possible to perform a direct stu…
Kaon photoproduction with form factors in a gauge-invariant approach
H. Haberzettl, C. Bennhold, T. Mart +1
The general gauge-invariant photoproduction formalism given by Haberzettl is applied to kaon photoproduction off the nucleon at the tree level, with form factors describing composi…
Vector Meson Photoproduction with an Effective Lagrangian in the Quark Model
Qiang Zhao, Zhenping Li, C. Bennhold
A quark model approach to the photoproduction of vector mesons off nucleons is proposed. Its starting point is an effective Lagrangian of the interaction between the vector meson a…
Higher Nucleon Resonances in Exclusive Reactions on Nuclei
Frank X. Lee, C. Bennhold, S. S. Kamalov +1
We report calculations for exclusive pion photoproduction on nuclei beyond the first resonance region in the distorted wave impulse approximation. The elementary operator contains…
Gauge-invariant tree-level photoproduction amplitudes with form factors
H. Haberzettl, C. Bennhold, T. Mart +1
We show how the gauge-invariance formulation given by Haberzettl is implemented in practice for photoproduction amplitudes at the tree level with form factors describing composite…
Vector Meson Photoproduction with an Effective Lagrangian in the Quark Model II: Photoproduction
Qiang Zhao, Zhenping Li, C. Bennhold
An investigation of is presented in a constituent quark model approach. The sparse data in the large region where the resonances dominate is well described within th…
and Photoproduction with an Effective Quark Model Lagrangian
Qiang Zhao, Zhenping Li, C. Bennhold
An unified approach for vector meson photoproduction is presented in the constit quark model. The s- and u-channel resonance contributions are generated using an effective quark ve…
Eta photoproduction
L. Tiator, G. Knoechlein, C. Bennhold
We present a combined analysis of the new eta photoproduction data for total and differential cross sections, target asymmetry and photon asymmetry. Using basic assumptions, this a…
