Download or read book Dynamical Coupled channels Effects on Pion Photoproduction written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The electromagnetic pion production reactions are investigated within the dynamical coupled-channels model developed in {\bf Physics Reports, 439, 193 (2007)}. The meson-baryon channels included in this study are $\gamma N$, $\pi N$, $\eta N$, and the $\pi\Delta$, $\rho N$ and $\sigma N$ resonant components of the $\pi\pi N$ channel. With the hadronic parameters of the model determined in a recent study of $\pi N$ scattering, we show that the pion photoproduction data up to the second resonance region can be described to a very large extent by only adjusting the bare $\gamma N \rightarrow N^*$ helicity amplitudes, while the non-resonant electromagnetic couplings are taken from previous works. It is found that the coupled-channels effects can contribute about 10 - 20 $\%$ of the production cross sections in the $\Delta$ (1232) resonance region, and can drastically change the magnitude and shape of the cross sections in the second resonance region. The importance of the off-shell effects in a dynamical approach is also demonstrated. The meson cloud effects as well as the coupled-channels contributions to the $\gamma N \rightarrow N^*$ form factors are found to be mainly in the low $Q^2$ region. For the magnetic M1 $\gamma N \rightarrow \Delta$ (1232) form factor, the results are close to that of the Sato-Lee Model. Necessary improvements to the model and future developments are discussed.

Download or read book Nuclear Pion Photoproduction written by Anton Nagl and published by Springer. This book was released on 2006-04-11 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoproduction of pions from complex nuclei has become an investigative tool for (1) the detailed form of the elementary photopion amplitude, (2) the pion-nucleus optical potential, (3) nuclear structure, and (4) off-shell and medium effects on the elementary amplitude in nuclear processes. In this book, all these aspects are considered in detail. With improved experimental accuracy and beam tech- nology the study of nuclear pion photoproduction will break new ground and become an even more powerful investigative tool. This monograph is intended as an introductory guide as well as a reference manual for grad- uate students and researchers working in this important area of physics.

This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the reaction on a 4 He target have been carried out using both unpolarised and polarised photons. This work is the latest in a series of experiments conducted by the Edinburgh University Nuclear Physics group in collaboration with the Universities of Glasgow and Tubingen. The experiment was carried out using the 855 MeV MAMIB electron accelerator at the Institut fur Kernphysik, Mainz, between March and August of 1996. The 855 MeV electrons from the accelerator were directed either, on to a 4 micron Nickel foil to produce unpolarised photons or on to a 0.1 mm Diamond to produce polarised photons. These photons were then tagged with a resolution of 2 MeV using a spectrometer. The photons then impinged on a 4 He cryotarget. Two sets of detectors were used to detect the reaction products. PiP, a plastic scintillator hodoscope, was used to detect the positive pions; and TOF a time of flight array, was used to detect the neutrons. Data was analysed for unpolarised photon energy regions centred at E =260,300,340 and 380 MeV and two polarised regions centred at E =258 and 338 MeV. The unpolarised data is presented as double and triple differential cross sec tions while the polarised data is presented as photon asymmetries of the corres ponding double differential cross section. A comparison is made with Plane Wave Impulse Approximation (PWIA) calculations by Louis Wright, both with and without final state interaction corrections. It is concluded that for the unpolar ised data a more sophisticated treatment of the final state interactions is required while for the polarised data reasonable agreement is found between experiment and theory.
