We present a measurement of asymmetries in the production of Λ c + and Λ c − baryons in 500 GeV/ c π − -nucleon interactions from the E791 experiment at Fermilab. The asymmetries were measured as functions of Feynman x ( x F ) and transverse m

Using data from Fermilab fixed-target experiment E791, we measure the branching ratio for D 0 → K − K + π − π + and its resonant components. We find Γ(D 0 →K − K + π − π + ) Γ(D 0 →K − π + π − π + ) =(3.13±0.37±0.36) %. A
