Photoproduction of cf) Mesons with Linearly Polarized Photons at LEPS/SPring-8 Experiment

摘要

Diffractive photoproduction of c/>-meson near threshold involves Pomeron exchange, pseudo-scalar exchanges and possible exotic components such as glueball and scalar-meson exchange Simultaneous measurements of cross section and decay asymmetry with linearly polarized photons make possible disentangling these mechanisms with different exchange parity We reported such a study by LEPS/SPring-8 experiment.
