The article contains new results for spin-3/2 and -1/2 resonances. It specializes to the second resonance region, which includes the P11(1440), D13(1520) and S11(1535) resonances. New data on electroproduction enable us to determine the vector form factors accurately. Estimates for the axial couplings are obtained from decay rates of the resonances with the help of the partially conserved axial...
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 کاملEntropy production by resonance decays.
We investigate entropy production for an expanding system of particles and resonances with isospin symmetry { in our case pions and mesons { within the framework of relativistic kinetic theory. A cascade code to simulate the kinetic equations is developed and results for entropy production and particle spectra are presented.
متن کاملElectromagnetic Meson Production in the Nucleon Resonance Region
Recent experimental and theoretical advances in investigating electromagnetic meson production reactions in the nucleon resonance region are reviewed. The article gives a description of current experimental facilities with electron and photon beams and presents an unified derivation of most of the phenomenological approaches being used to extract the resonance parameters from the data. The anal...
متن کاملParametric Resonance in Oscillations of Atmospheric Neutrinos?
We consider a solution of the atmospheric neutrino problem based on oscillations of muon neutrinos to sterile neutrinos: νμ ↔ νs. The zenith angle (Θ) dependences of the neutrino and upward-going muon fluxes in presence of these oscillations are studied. The dependences have characteristic form with two dips: at cosΘ = −0.6÷−0.2 and cosΘ = −1.0÷−0.8. The latter dip is due to parametric resonanc...
