We propose to study the ep -> ep reaction at three dierent Q2: 0.1, 0.2 and 0.5 GeV2, where there are no experimental data. The unpolarized cross section will be measured below the pion production threshold, with the electron beam at MAMI-C energies, using the A1 detector setup and the hydrogen target. We plan to use two analysis techniques, in order to produce the most complete set of data for the physicsobservables. High statistics will ensure competitive error bars. These new data will be an essential piece to build a consistent picture of the Q2- dependence of the VCS structure functions and the generalized polarizabilities to constrain the theoretical models and ultimately improve our understanding of the nucleon electromagnetic structure.

Abstract
We propose to study the ep -> ep reaction at three dierent Q2: 0.1, 0.2 and 0.5 GeV2, where there are no experimental data. The unpolarized cross section will be measured below the pion production threshold, with the electron beam at MAMI-C energies, using the A1 detector setup and the hydrogen target. We plan to use two analysis techniques, in order to produce the most complete set of data for the physicsobservables. High statistics will ensure competitive error bars. These new data will be an essential piece to build a consistent picture of the Q2- dependence of the VCS structure functions and the generalized polarizabilities to constrain the theoretical models and ultimately improve our understanding of the nucleon electromagnetic structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
