  "abstract": "We present a measurement of asymmetries in the production of $\\Lambda_c^+$ and $\\Lambda_c^-$ baryons in 500 GeV/c $\\pi^-$--nucleon interactions from the E791 experiment at Fermilab. The asymmetries were measured as functions of Feynman x ($x_F$) and transverse momentum squared ($p_T^2$) using a sample of $1819 \\pm 62$ $\\Lambda_c$'s observed in the decay channel $\\Lambda_c \\to pK^-\\pi^+$. We observe more $\\Lambda_c^+$ than $\\Lambda_c^-$ baryons, with an asymmetry of $(12.7\\pm3.4\\pm1.3) %$ independent of $x_F$ and $p_T^2$ in our kinematical range $(-0.1 < x_F < 0.6$ and $0.0 < p_T^2 < 8.0 (GeV/c)^2$). This $\\Lambda_c$ asymmetry measurement is the first with data in both the positive and negative $x_F$ regions.",
