This book was released on 2016 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-spherical components of the nucleon wave function are measured through p(e, e'p)[pi]0 experiment at the [Delta]+(1232) resonance for Q2 = 0.04, 0.09, and 0.13 (GeV=c)2 utilizing the Jefferson National Accelerator Facility (JLab) pulsed beam and Hall A spectrometers. The new data extend the measurements of the Coulomb quadrupole amplitude to the lowest momentum transfer ever reached. The results disagree with predictions of constituent quark models and are in reasonable agreement with dynamical calculations that include pion cloud effects, chiral effective field theory and lattice calculations. The reported measurements indicate that improvement is required to the theoretical calculations and provide valuable input that will allow their refinements. The Coulomb to magnetic multipole ratio (CMR) and generalized polarizability (GP) of the nucleon are also measured through virtual Compton scattering (VCS) for Q2 = 0.2(GeV=c)2 utilizing the Mainz Microtron (MAMI) continuous beam and A1 spectrometers. This data represents the first low Q2 GP measurement at the [Delta]+(1232) resonance. The GP measurement explores a region where previous data and theoretical calculations disagree. The CMR measurement will be the first VCS extraction to compare with world data generated through pion electroproduction. The Dispersion Relation (DR) model used for the VCS extraction provides a new theoretical framework for the data signal and backgrounds that is largely independent from the pion electroproduction models. The independence of the DR from the traditional models provides a strong crosscheck on the ability of the models to isolate the data signal.

Download or read book High Energy Physics written by E Burhop and published by Elsevier. This book was released on 2012-12-02 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Energy Physics, Volume V is a collection of papers that discusses photo- and electro-production processes, Reggae phenomenology, and quantum electrodynamics. The book explains the details involved in pion photo-production and electro-production, such as the kinematics, the choice of invariant amplitudes, the multipole amplitude, helicity amplitude expansions of the transition matrix, cross section, polarization formulas. The text also discusses high energy phenomenology using Regge poles, particularly on finite energy sum rules (FESR), duality, the Veneziano model, and Regge cuts. The Veneziano model, a form of amplitude combining low energy resonances and high energy Regge behavior in an analytic and crossing-symmetric ways, satisfies FESR. The model also provides a true realization of duality. The book analyzes evidence on the validity of quantum electrodynamics showing no grave discrepancies that are present between quantum electrodynamics and experiments. The text then describes the low energy tests and the high energy tests (including those with storage rings). The book can prove useful for theoretical physicists, investigators of quantum mechanics, and professors of advance physics.

Download or read book Adventures in Theoretical Physics written by Stephen L. Adler and published by World Scientific. This book was released on 2006 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the period 1964-1972, Stephen L. Adler wrote seminal papers on high energy neutrino processes, current algebras, soft pion theorems, sum rules, and perturbation theory anomalies that helped lay the foundations for our current standard model of elementary particle physics. These papers are reprinted here together with detailed historical commentaries describing how they evolved, their relation to other work in the field, and their connection to recent literature. Later important work by Dr. Adler on a wide range of topics in fundamental theory, phenomenology, and numerical methods, and their related historical background, is also covered in the commentaries and reprints. This book will be a valuable resource for graduate students and researchers in the fields in which Dr. Adler has worked, and for historians of science studying physics in the final third of the twentieth century, a period in which an enduring synthesis was achieved.
