\pi N TDAs from charmonium production in association with a forward pion at PANDA

Abstract

Charmonium production in association with a forward or backward pion in nucleon-antinucleon annihilation is one of the most promising reaction to access nucleon-to-pion transition distribution amplitudes (TDAs) at PANDA. We briefly review the description of this reaction in terms of \pi N TDAs within the collinear factorization approach and present the first results of dedicated feasibility studies for the PANDA experimental setup.
