Comparing phenomenological recipes with a microscopic model for the electric amplitude in strangeness photoproduction
A. Yu. Korchin, O. Scholten
Corrections to the Born approximation in photo-induced strangeness production off a proton are calculated in a semi-realistic microscopic model. The vertex corrections and internal…
Virtual-pion and two-photon production in pp scattering
O. Scholten, A. Yu. Korchin
Two-photon production in pp scattering is proposed as a means of studying virtual-pion emission. Such a process is complementary to real-pion emission in pp scattering. The virtual…
Covariant model for proton-proton bremsstrahlung: Comparison with high-precision data
M. D. Cozma, G. H. Martinus, O. Scholten +2
We compare a relativistic covariant model for proton-proton bremsstrahlung with high-quality data from KVI. The agreement in large parts of phase space is satisfactory. However, re…
Coherent Compton scattering on light nuclei in the delta resonance region
L. Van Daele, A. Yu. Korchin, D. Van Neck +2
Coherent Compton scattering on light nuclei in the delta resonance region is studied in the impulse approximation and is shown to be a sensitive probe of the in-medium properties o…
Low-energy Compton scattering on the nucleon and sum rules
S. Kondratyuk, O. Scholten
The Gerasimov-Drell-Hearn and Baldin-Lapidus sum rules are evaluated in the dressed K-matrix model for photon-induced reactions on the nucleon. For the first time the sum of…
Photoproduction of electron-positron pairs on the proton in the resonance region
A. Yu. Korchin, O. Scholten
Production of lepton pairs in gamma p -> e-e+ p reaction is studied at photon energies up to 1 GeV. We show that even if lepton charge is not measured there are extensive kinematic…
