Quasifree Kaon Photoproduction on Nuclei
Investigations of the quasifree reaction A(γ,KY )B are presented in the distorted wave impulse approximation (DWIA). For this purpose, we present a revised tree-level model of elementary kaon photoproduction that includes hadronic form factors, uses SU(3) values for the Born couplings and gives a good description of all available data. The potential of exclusive quasifree kaon photoproduction o...
متن کاملLow energy kaon photoproduction from nuclei ∗
We study K +-meson production in γA interaction at energies below the reaction threshold in free space. The Thomas-Fermi and spectral function approaches are used for the calculations of the production process. It is found that the measurement of the differential spectra may allow to reconstruct the production mechanism and to investigate the dispersion relations entering the production vertex....
متن کاملEvidence for a Missing Nucleon Resonance in Kaon Photoproduction
New SAPHIR p(γ, K +)Λ total cross section data show a resonance structure at a total c.m. energy around 1900 MeV. We investigate this feature with an isobar model and find that the structure can be well explained by including a new D 13 resonance at 1895 MeV. Such a state has been predicted by a relativistic quark model at 1960 MeV with significant γN and KΛ branching ratios. We demonstrate how...
