Title: Charm Baryon Studies at BABAR

Abstract

We present a precision measurement of the mass of the {lambda}{sub c}{sup +} and studies of the production and decay of the {omega}{sub c}{sup 0} and {xi}{sub c}{sup 0} charm baryons using data collected by the BABAR experiment. To keep the systematic uncertainty as low as possible, the {lambda}{sub c}{sup +} mass measurement is performed using the low Q-value decays, {lambda}{sub c}{sup +} {yields} {lambda}{sup 0}K{sub S}{sup 0}K{sup +} and {lambda}{sub c}{sup +} {yields} {sigma}{sup 0}K{sub S}{sup 0}K{sup +}. Several hadronic final states involving an {omega}- and a {xi}- hyperon are analyzed to reconstruct the {xi}{sub c}{sup 0} and the {omega}{sub c}{sup 0}.
