Abstract
Recently several proposals were put forward to determine the parity of narrow baryonic resonances, in particular the Θ+. In these proceedings we will briefly comment on the general problems in this task and then discuss in detail the potential of reactions of the type N NΘ+Y, where Y denotes a hyperon (either Σ or Λ) and the arrows indicate that a polarized initial state is required. Besides reiterating the model--independent properties of this class of reactions we discuss the physics content of some model calculations.
