First charm baryon physics from SELEX(E781)

PDF Version Also Available for Download.

Description

We present preliminary results on various aspects of charm baryon studies at the 1996-1997 fixed target experiment of Fermilab studying charm produced from incident {Sigma}{sup -}, proton, and {pi}{sub -} beams at 600 GeV. First results include the comparison of hadroproduction asymmetries for {Lambda}{sub c}{sup +} production from the 3 beams as well xF distributions and the first observation of the Cabbibo-suppressed decay {Xi}{sub c}{sup +} {yields} pK{sup -}{pi}{sup +}. The relative branching fraction of the Cabbibo-suppressed mode to the 3-body Cabbibo-favored modes is also presented.
