Physics at ELSA

Abstract

Recent experimental results of the Crystal-Barrel/TAPS collaboration at ELSA are presented. The experiments used a tagged photon beam incident on proton and neutron targets. Multiple photon final states were detected in the hermetically closed Crystal-Barrel/TAPS detector setup, enabling the reconstruction of various neutral meson production channels. In addition to cross sections also photon beam asymmetries and, in the $K_s^0{\Sigma }^{+}$ channel, recoil polarisations were determined.
