We report on the improvement of our isobar models for elementary kaon photo- and electroproduction, \(\gamma _\mathrm{r,v}+N\rightarrow K+Y\), during the last two decades.Our effort started with the investigation of kaon photoproduction near threshold, followed by the construction of new models which were intended to explain all \(K\Lambda \) and \(K\Sigma \) data from threshold up to \(W. It's based on laws of science and reflects the very structure of nature. As a musician, it's important to understand at least the basics of how music works; that is, the basics of acoustics. This is because understanding the science of music, will help you better appreciate why music theory is the way it is. 1 Prelinger Archives View thousands of films from the Prelinger Archives!

ELECTROPRODUCTION of the N 0 (1535) RESONANCE at LARGE MOMENTUM TRANSFERS Vladimir M. Braun1 Institut für Theoretische Physik Universität Regensburg = [ The electroproduction of H 2 O 2 through 2e oxygen reduction reaction (ORR) as an alternative strategy for the conventional anthraquinone process is highly energy-efficient and environment-friendly. Different kinds of electrocatalysts with high selectivity, activity, and stability have been recently reported, and are an essential part of the whole electroproduction process of H 2 O 2 Quadrupole amplitudes in the γ * N→∆ transition are associated with the issue of nucleon deformation. A search for these small amplitudes has been the focus of a series of measurements undertaken at Bates/MIT by the OOPS Collaboration. We report on results from H(e,e'p)π 0 data obtained at Q 2 =0.070 (GeV/c) 2</SUP> and invariant mass of W=1155 MeV using the out-of-plane detection.

Here we present high-efficiency ethylene electroproduction from CO on copper at current densities above 100 mA cm −2. The system performs well across a wide range of input CO concentrations A high resolution study of the H(e,e'K+)Λ,Σ0 reaction was performed at Hall A, TJNAF as part of the hypernuclear experiment E94-107. One important ingredient to the measurement of the hypernuclear cross section is the elementary cross section for production of hyperons, Λ and Σ0. This reaction was studied using a hydrogen (i.e. a proton) target. Data were taken at very low Q2 (∼0.07 (GeV. The analysis of the nine 1-fold differential cross sections for the γ r, v p → π + π − p photo- and electroproduction reactions obtained with the CLAS detector at Jefferson Laboratory was carried out with the goal to establish the contributing resonances in the mass range from 1.6 GeV to 1.8 GeV. In order to describe the photo- and electroproduction data with Q 2-independent resonance.

We report the first longitudinal-transverse separation of the deeply virtual exclusive π 0 electroproduction cross section off the neutron and coherent deuteron. The corresponding four structure functions d σ L /d t , d σ T /d t , d σ L T /d t , and d σ T T /d t are extracted as a function of the momentum transfer to the recoil system at Q 2 =1.75 GeV 2 and x B =0.36 An approximate evaluation is made of the dispersion relations for the production of pions in electron-nucleon collisions. The results are applicable at low energies in the final pion-nucleon barycentric system where the assumption that the (3, 3) state dominates the dispersion integrals is expected to be valid. Effects due to nuclear recoil and crossing symmetry are treated exactly to all orders
