Abstract
A novel approach that allows access to long-sought information on the
Hyperon-Nucleon (YN) interaction was developed by producing a hyperon
beam within a few-body nuclear system, and studying final-state
interactions. The determination of polarisation observables, and
specifically the beam spin asymmetry, in exclusive reactions allows a
detailed study of the various final-state interactions and provides us
with the tools needed to isolate kinematic regimes where the YN
interaction dominates. High-statistics data collected using the CLAS
detector housed in Hall-B of the Thomas Jefferson laboratory allows us
to obtain a large set of polarisation observables and place stringent
constraints on the underlying dynamics of the YN interaction.
