Charm production asymmetries from heavy-quark recombination

Abstract: Abstract. Charm asymmetries in fixed-target hadroproduction experiments are sensitive to power corrections to the QCD factorization theorem for heavy quark production. A power correction called heavy-quark recombination has recently been proposed to explain these asymmetries. In heavy-quark recombination, a light quark or antiquark participates in a hard scattering which produces a charm-anticharm quark pair. The light quark or antiquark emerges from the scattering with small momentum in the rest frame of the … Show more

“…where is a parameter that scales as m −2 Q ( c ≈ 0.05, b ≈ 0.006). Recombination In proton-proton collisions, heavy quarks can hadronize into mesons by the recombination with a light quark in the proton remnant [209]. In a heavy-ion collision, the recombination mechanism plays a far more essential role for low p T heavy flavors, given the abundance of thermal medium partons.…”
