Measurement of double polarisation asymmetries in ω-photoproduction

Measurement of double polarisation asymmetries in ω-photoproduction

The first measurements of the beam-target-helicity-asymmetries E and G in the photoproduction of ω-mesons off protons at the CBELSA/TAPS experiment are reported. E (G) was measured using circularly (linearly) polarised photons and a longitudinally polarised target. E was measured over the photon ene...
