Abstract
We study the reaction with some kinematics suited to the production of the resonance recently observed. We show that, independently of the quantum numbers of the , a resonance signal is always observed in the forward direction. In addition, we also show how a combined consideration of the strength at the peak, and the angular dependence of polarization observables can help determine the quantum numbers using the present reaction.
