I. Mokeev, V. D. Burkert, T. -S. H. Lee, L. Elouadrhiri, G. V. Fedotov, and B. S. Ishkhanov<br/>Recent CLAS data on the pπ^{+} π^{-} electroproduction off protons at 1.3<W<1.57 GeV and 0.25<Q^{2} <0.6 GeV^{2} have been analyzed using a meson-baryon phenomenological model. By fitting nine onefold differential cross-section data for each W and Q^{2} bin, the charged double-pion electroproduction mechanisms are identified from their manifestations in the observables. We have extracted the cross sections from amplitudes of each of the considered isobar channels as well as from their coherent sum. We also obtained nonresonant partial wave amplitudes of all contributing isobar channels that could be useful for advancing a complete coupled-channels analysis of all meson electroproduction data.<br/>[Phys.

CLAS Collaboration<br/>We report measurements of the beam spin asymmetry in deeply virtual Compton scattering (DVCS) at an electron beam energy of 4.8 GeV using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The DVCS beam spin asymmetry has been measured in a wide range of kinematics, 1.0<Q^{2} <2.8 (GeV/c)^{2} , 0.12<x_{B} <0.48, and 0.1<-t<0.8 (GeV/c)^{2} , using the reaction e [over →] p→e^{'} pX. The number of H(e,e^{'} γp) and H(e,e^{'} π^{0} p) events are separated in each (Q^{2} ,x_{B} ,t) bin by a fit to the line shape of the H(e,e^{'} p)X M_{x}^{2} distribution. The validity of the method was studied in detail using experimental and simulated data. It was shown that with the achieved missing mass squared resolution and the available statistics, the separation of DVCS–Bethe-Heitler and π^{0} events can reliably be done with less than 5% uncertainty. Also, the Q^{2} and t dependences of the sinϕ moments of the asymmetry are extracted and compared with theoretical calculations.<br/>[Phys. Rev. C 80, 035206] Published Tue Sep 29, 2009 G.
