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...

Title: Computing the Pion Light-Cone Distribution Amplitude Using the Heavy-Quark Operator Product Expansion
Abstract: The light-cone distribution amplitude (LCDA) of the pion carries information about the momentum distribution of its quarks, which is an important input to various experiments. The LCDA can be expanded in terms of its Mellin...
