Title: Shedding Light on Shadow Generalized Parton Distributions
Abstract: The feasibility of extracting generalized parton distributions (GPDs) from deeply virtual Compton scattering (DVCS) data has recently been questioned because of the existence of an infinite set of so-called “shadow GPDs” (SGPDs). These SGPDs depend on the...
Abstract: Parity-violating experiments like P2 at Mainz Energy-Recovering Superconducting Accelerator (MESA) demand accuracy of polarization measurement of ¿P/P < 1 %. To ensure electron beam polarization, a polarimetry chain with polarimeters at different energies is planned. This will help to track the beam polarization throughout the MESA lattice. A 5 MeV Mott polarimeter is planned as a part of the chain. This polarimeter is planned to run parallel to the Moller polarimeter and P2 experiment...
