Abstract

We report very preliminary results of a Dalitz-plot analysis of Lambda_c+ in the decay to p K- pi+ with the helicity formalism. We used the data from the fixed target experiment SELEX (E781) in Fermilab. We report about branching-ratios of the resonant states involved, and a possible initial state polarization.
