Study of the Hyperon-Nucleon (YN) Interaction in Exclusive Λ Photoproduction off the Deuteron

Abstract

This study aims to extract the polarization observables Cx, Cz, ∑, Ox, and Oz for final-state interactions (FSI) in γ→d→K+Λ→n$\overrightarrow \gamma d \to {K^ + }\overrightarrow \Lambda n$. The data were taken with the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility (JLab) during the E06-103 experiment. These are the very first results for FSI observables in hyperon photoproduction and are expected to constrain the free parameters of YN potentials.
