Abstract

With the first evidence of direct CP violation in D0K+K/π+πD^0 \to K^+K^-/\pi^+\pi^- there is a strong reason to probe CP asymmetries in charm baryons in three-body final states Λcpπ+π/pK+K\Lambda_c \to p\pi^+\pi^-/pK^+K^- & ΛcpK+π\Lambda_c \to pK^+\pi^- with ΛcpKπ+\Lambda_c \to pK^-\pi^+ to calibrate them. Analyzing the Dalitz plots carefully allows to find the 'existence' of New Dynamics (ND) and its `features'. One can test different methods to probe CP asymmetries. Final data from CDF and D0 experiments have advantage by comparing Λc\Lambda_c with Λˉc\bar \Lambda_c directly from ppˉp \bar p collisions. LHCb will need more data with Λˉc\bar \Lambda_c transitions.
