Probing hard/soft factorization via beam-spin asymmetry in exclusive pion electroproduction from the proton

Alicia C. Postuma, Garth M. Huber, D. J. Gaskell +76

Deep exclusive meson production (DEMP) reactions, such as $p(\vec{e},e^{\prime }\ddot{I}{€}^{+})n$, provide opportunities to study the three-dimensional structure of the nucleon through differential c…
