Nucleon and resonances in K (1385) photoproduction from nucleons
نویسندگان
چکیده
The reaction mechanisms for K (1385) photoproduction from the reaction γp → K+ 0(1385) in the resonance energy region are investigated in a hadronic model. Both contributions from N and resonances of masses around 2 GeV as given in the Review of Particle Data Group and by the quark model predictions are included. The Lagrangians for describing the decays of these resonances into K (1385) are constructed with the coupling constants determined from the decay amplitudes predicted by a quark model. Comparing the resulting total cross section for the reaction γp → K+ 0(1385) with the preliminary data from the Thomas Jefferson National Accelerator Facility, we find that the most important contributions are from the two-star-rated resonances (2000)F35, (1940)D33, and N (2080)D13, as well as the missing resonance N 32 − (2095) predicted in the quark model. Predictions on the differential cross section and photon asymmetry in this reaction are also given.

Final State Interactions in Ω Photoproduction near Threshold Yongseok Oh
Vector meson photoproduction and electroproduction have been suggested as a tool to find or confirm the nucleon resonances. In order to extract more reliable informations on the nucleon resonances, understanding the non-resonant background is indispensable. We consider final state interactions in ω photoproduction as a background production mechanism. For the intermediate states, we consider nu...
متن کاملMissing Resonances in Kaon Photoproduction on the Nucleon
New kaon photoproduction data on a proton, γ + p → K + Λ, are analyzed using a multipole approach. The background terms are given in terms of gauge invariant, crossing symmetric, Born diagrams with hadronic form factors, while the resonances are parameterized using Breit-Wigner forms. Preliminary results suggest a number of new resonances, as predicted by many quark model studies. A comparison ...
متن کاملAnalyzing Η Photoproduction Data on the Proton at Energies of 1.5–2.3 Gev
One of the primary interests in investigating η meson-production reactions is that they may be suited to extract information on nucleon resonances, N, in the less-explored higher N mass region. Current knowledge of most of the nucleon resonances is mainly due to the study of πN scattering and/or pion photoproduction off the nucleon. Since the η meson is much heavier than a pion, η meson-product...
متن کاملMeson photoproduction in the first and second resonance region
The study of baryon resonances via meson photoproduction reactions on the free proton and on nucleons in the nuclear medium is discussed. Special emphasis is laid on the production of neutral mesons which due to the suppression of nonresonant backgrounds are particularly well suited for the study of excited states of the nucleon. Experiments carried out during the last ten years with the TAPSde...
متن کاملStudy of Nucleon Resonances with Double Polarization Observables of Pion Photoproduction
The role of the nucleon resonances in the double polarization observables of pion photoproduction is investigated by using the resonance parameters predicted by Capstick and Roberts. As an example, we show that the not-welldetermined two-star resonance N−3/2(1960) can be examined by performing experiments on beam-recoil polarization at large angles.
