First analysis of hard exclusive data using the HERMES Recoil Scintillating Fiber Tracker — •Tibor Keri, Michael Dueren, Roberto Francisco Perez-Benito, and Weilin Yu — II.Physikalisches Institut, Justus-Liebig-Universitaet, Giessen, Hessen, Deutschland

The HERMES experiment was upgraded by a Recoil Detector that contains a Scintillating Fiber Tracker in order to measure recoiling protons and pions with low momentum and at large polar angle. The upgrade improves the event selections of hard-exclusive processes and helps to access Generalized Parton Distributions. Preliminary studies to extract single spin asymmetries of DVCS processes were carried out and first results will be presented.
