Threshold π0 photoproduction on transverse polarised protons at MAMI

Threshold π0 photoproduction on transverse polarised protons at MAMI

Polarisation-dependent differential cross sections σT associated with the target asymmetry T have been measured for the reaction γp→→pπ0 with transverse target polarisation from π0 threshold to photon energies of 190 MeV. The data were obtained using a frozen-spin butanol target with the Crystal Bal...
