First measurements of γ p → K⁺ Λ at extreme forward angles at the BGO-OD experiment* — •Thomas Zimmermann for the BGO-OD collaboration — Physikalisches Institut, Universität Bonn

The BGO-OD experiment, located at the electron accelerator ELSA at the University of Bonn, is designed to study nucleon excitations with emphasis on understanding the reaction dynamics. One reaction of major interest is γ p → K⁺ Λ. The BGO-OD experiment is ideal to investigate the dominant t-channel mechanisms in this reaction channel at forward angles due to the high resolution and acceptance of the forward spectrometer. The new data currently being analyzed covers extremely forward angles with high resolution. This will constrain solutions from data driven models and analysis, such as PWA and isobar models.
