Book Description
The differential cross sections and the single beam asymmetries have been measured for the single pion electroproduction on the proton at Q2 = 0.4 GeVZ using CLAS. The large phase space coverage of CLAS and the high statistical accuracy of the data allowed us to perform the analysis of single pion electroproduction observables and to obtain the A1/2 amplitudes for the S11(1535). The preliminary results of this analysis are in good agreement with the {eta}-meson production data.

Book Description
Analysis of the single pion electroproduction data is one of the most powerful tools in investigating the nucleon resonances in the first and second resonance regions. Recent pion electroproduction experiments using CLAS detector at Jefferson Lab for the first time provides us with data for the cross sections and the single beam spin asymmetries for both epto e' n pi^+ and epto e' p pi^0 channels. In order to analyze this data an analysis program based on the Mainz unitary isobar model was developed at Jefferson Lab. The single pion electroproduction cross sections and the single beam asymmetry data were fitted simultaneously to obtain the resonant amplitudes for the excited states in the first two nucleon resonance regions. Preliminary results will be presented for the electroproduction amplitudes for the S_11(1535) and D_13(1520) resonances.

Book Description
Single pion electroproduction in the resonance region has been studied as a means of exploring the physics underlying the structure of the nucleon. Recent experiments using CLAS at Jefferson Lab/Hall B have measured unpolarized cross sections and beam spin asymmetries over a large kinematic range. The high statistical accuracy of this data set provides important information on the Delta(1232) and the Roper.

Book Description
This book deals with the latest developments in the area of three-quark systems. Emphasis is given to the discussion of new experimental results in the areas of form factors, unpolarized and polarized structure functions, and baryon structure and spectroscopy. Of particular interest are the new theoretical developments in the area of generalized parton distributions and lattice quantum chromodynamics.

Book Description
Electroproduction data from CLAS at Jefferson Lab are being analyzed in order to identify resonant couplings to baryon resonances decaying into {pi}{Delta}, pN, or {omega}N. A multi-dimensional fit to the new two-pion electroproduction data not only provides better determined photocouplings of several resonances, but also implicates a significant correction of the hadronic couplings of resonances at W approx. 1.7 GeV. The electroproduction of w shows strong indications of u- and s-channel contributions at W below 2 GeV.
