Experimental tests of QCD scaling laws at large momentum transfer in exclusive light-meson photoproduction

Experimental tests of QCD scaling laws at large momentum transfer in exclusive light-meson photoproduction

We evaluated CLAS Collaboration measurements for the 90° meson photoproduction off the nucleon using a tagged photon beam spanning the energy interval s = 3–11 GeV2. The results are compared with the “quark counting rules” predictions.
