Strong two-body decays of the Λc(2940)+ in a hadronic molecule picture

Abstract

The Λc(2940)⁺ baryon with possible quantum numbers JP=12⁺ and 12^- is studied as a molecular state composed of a nucleon and D* meson. We give predictions for the strong two-body decay channels Λc(2940)⁺→pD0, Σc++π^- and Σc0π⁺, where the sum of partial widths is consistent with current data for the case of JP=12⁺. The case of JP=12^- is shown to be ruled out.
