Evidence for CP violation in baryonic decays has not been seen in experiments. With large data events accumulated at e+e− collider or Large Hadron Collider, the charmed baryon decays would provide a promising laboratory to test the CP symmetry. In this work, we formulate the Λc+→ϕp and Λc+→ωp decays for the measurements of their asymmetry parameters in weak decays at the BESIII or the LHCb experiments. The polarization transfer is analyzed in the two processes of e+e−→Λc+Λˉc− and Λb0→Λc+π−, and the formulas of the joint angular distribution for these processes are provided. The sensitivity of the measurement of asymmetry parameters for the above two decay processes is estimated for the future experiments.
