$\Lambda_c^+/\Lambda^-_c$ Asymmetry in Hadroproduction for Heavy-Quark Recombination


Journal Article (Academic article)

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_c^+/\Lambda_c^- asymmetries measured in \pi N and p N collisions.
