This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Pion Electroproduction Off The Deuteron by : Mahmoud Tammam
Download or read book Pion Electroproduction Off The Deuteron written by Mahmoud Tammam and published by LAP Lambert Academic Publishing. This book was released on 2014-09-25 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is the first step of a systematic study of incoherent electroproduction of pion mesons off the deuteron in the (1232) resonance region, it is taken by restriction to the impulse approximation, i.e., neglecting pion rescattering and two-body effects. The elementary operator for pion electroproduction from the nucleon is taken from the unitary isobar model (MAID) which is a model for single pion photo- and electroproduction off protons and neutrons. This approximation corresponds to the so-called spectator model in which the pion production takes place on a single nucleon inside the deuteron while the other nucleon acts merely as a spectator.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of pion electroproduction on the deuteron carried out by the ANL group at ALS, Saclay, show that even in the weakly-bound deuteron, multinucleon processes alter the electroproduction amplitudes in the forward direction. The data provide the first experimental indications for a significant change in the pion-nucleon coupling for nucleons bound in nuclei. It is clear that forward-angle electroproduction may be a sensitive probe of the properties of the pion coupling in the nuclear medium. At CEBAF, we will study longitudinal charged-pion electroproduction (in the excitation region below the delta isobar) along the direction of the momentum transfer where the charge scattering process dominates. Direct comparison of the cross section per nucleon in deuterium and the helium isotopes with the experimental value for the free nucleon will provide estimates of the strength of the nuclear pion field. A Rosenbluth separation of the longitudinal and transverse cross sections will be performed for four-momentum transfers of 2.5 and 10 fm−2. Measurements for a number of light nuclei will provide useful data on the sensitivity of longitudinal electroproduction to nuclear binding effects. If current conceptions of pion-exchange currents in nuclei are correct, longitudinal electroproduction will be suppressed at the lower momentum transfer and enhanced at the higher momentum transfer by multinucleon processes. If on the other hand, as suggested by recent data from Drell-Yan studies of antiquark structure functions, there is no such enhancement, a reformulation of pion exchange models of the medium- and short-range properties of nuclear forces will be required. Our proposal to carry out such a series of measurements at CEBAF using the coincident-pair spectrometer system planned for Hall C was approved. Pions will be observed in the short-orbit spectrometer (SOS) which will serve as the second arm.

Book Synopsis Pion Electroproduction in the Second Resonance Region Using CLAS. by : Inna Aznauryan
Download or read book Pion Electroproduction in the Second Resonance Region Using CLAS. written by Inna Aznauryan and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Electroproduction of Pions in the Delta Region Within Dispersion Relation Approach by :
Download or read book Electroproduction of Pions in the Delta Region Within Dispersion Relation Approach written by and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is shown that fixed-t dispersion relations can be used for the separation of the resonance and nonresonance contributions to the multipole amplitudes M{sub 1+}32, E{sub 1+}32, S{sub 1+}32 within the interpretation on the language of diagram approach, dynamical models and effective Lagrangian approach. Within the dispersion relation approach the TJNAF data on the exclusive p(e, e'p)[pi]° reaction at Q2 = 2.8 and 4.0 (GeV/c2) are analysed in order to find the P33(1232) resonance contribution to the multipole amplitudes M{sub 1+}32, E{sub 1+}32, S{sub 1+}32. The comparison of the obtained results for the E{sub 1+}32/M{sub 1+}32 ratio with the data at low Q2 shows that there is no evidence for the presence of a visible pQCD contribution to the transition [gamma]N --> P33(1232) at Q2 = 3-4 GeV2. The results for the transverse form factor G{sub T}(Q2) of the [gamma]* N 2!P33(1232) transition show that with increasing Q2, Q4G{sub T}(Q2) decreases, so there is no evidence for the presence of the pQCD contribution here too.
