Exclusive two pion production — •Nikolaus Warkentin1, Dmitri Ivanov2, and Andreas Schäfer1 — 1Institut fuer Theoretische Physik,Universitaet Regensburg, D-93040 Regensburg — 2Sobolev Institute of Mathematics RAS, Novosibirsk 630090, Russia
The recent HERMES data for the exclusive two pion production are in good agreement with theoretical predictions at leading order. This and the expectation of new data from the COMPASS experiment motivated us to analyze the angular distribution in the process of exclusive electroproduction of pion pairs, using the collinear factorization approach at next-to-leading order.
