Strangeness Photoproduction on Quasifree Neutrons

Abstract

Strangeness photoproduction in the elementary reactions $\gamma N\to KY$ offers the possibility to study nucleon resonances in the mass region above 1.7 GeV, where the number of states and their properties are still under debate. These reactions could allow the first 'complete' experiment in pseudoscalar meson photoproduction due to the easier access to recoil polarization observables in experiments. In addition to measurements on proton targets, a full isospin decomposition of the $I=1/2$ electromagnetic amplitudes requires also data obtained from quasifree neutron targets. This contribution shows first preliminary results on feasibility studies for such measurements at the A2 experiment at MAMI.

Contribution to the proceedings of the 10th International Workshop on the Physics of Excited Nucleons - NSTAR2015, 25-28 May 2015, Osaka, Japan, to be published in JPS conference proceedings
