{Lambda}{sub c}{sup +}/{Lambda}{sub c}{sup -} Asymmetry in Hadroproduction from Heavy-Quark Recombination

Journal Article · · Physical Review D
OSTI ID:837022
Asymmetries in the hadroproduction of charm particles directly probe power corrections to the QCD factorization theorems. In this paper, the heavy-quark recombination mechanism, a power correction that explains charm meson asymmetries, is extended to charm baryons. In this mechanism, a light quark participates in the hard scattering that creates a charm quark and they hadronize together into a charm baryon. This provides a natural and economical explanation for the {Lambda}{sub c}{sup +}/{Lambda}{sub c}{sup -} asymmetries measured in piN and pN collisions.
