Plenary Plenary Session

Speaker

Igor Strakovsky (The George Washington University)

Description

We evaluated recent CLAS Collaboration measurements for the 90 deg meson photoproduction off the nucleon using a tagged photon beam spanning the energy interval s = 3 - 11 GeV^2. The results are compared with the Quark Counting Rules (QCR). predictions. Since Sudakov form factor is absent in the case of photoproduction these processes allows a better check/study of the QCR.
