Book Description
The goal of our research is to provide the exclusive [gamma]*(n) → p+[pi]- reaction cross section from deuterium data using the correction factor that account for the final state re-scattering that can be determined from the data set itself. The "e1e" Jefferson Lab CLAS data set that we analyze includes both a hydrogen and deuterium target run period, which allows a combined analysis of pion electroproduction off the free proton, the bound proton, and the bound neutron under the same experimental conditions. Hence it will provide the experimentally best possible information about the off-shell and final state interaction effects in deuterium, which must be considered in order to extract the neutron information. This data set will provide results with a kinematic coverage for the hadronic invariant mass W up to 1.7 GeV and in the momentum transfer Q2 range of 0.4 - 1.0 GeV/c2. The cross section analysis of this data set is currently underway, which will considerably improve our knowledge of the Q2 evolution of [pi]-p electroproduction cross sections off bound neutron needed for the extraction of excited neutron state electrocouplings for the first time.

Book Description
We report the analysis status of single [pi]0 electroproduction in the resonance region to study the electromagnetic excitation of the nucleon resonances. The study is aimed at understanding of the internal structure and dynamics of the nucleon. The experiment was performed using an unpolarized cryogenic hydrogen target and 2.0 and 5.8 GeV polarized electron beam during the e1e and e1-6 run periods with CLAS at Jefferson Lab. The new measurements will produce a data base with high statistics and large kinematic coverage for the hadronic invariant mass (W) up to 2.0 GeV in the momentum transfer (Q2) range of 0.3--6.0 GeV2. Preliminary results will be presented and compared with the various model calculations.
