Precise QCD Predictions for Hadron-in-Jet Production in e + e − Collisions
Abstract
The production of identified hadrons inside jets in e^{+}e^{-} annihilation allows for detailed studies of parton-to-hadron fragmentation functions in a clean environment. We compute hadron-in-jets production cross sections for e^{+}e^{-}→2 jets and e^{+}e^{-}→3 jets to next-to-next-to-leading order (NNLO) in perturbative QCD. By comparing with data from the ALEPH experiment, we demonstrate the implications of the newly computed theory predictions for precision phenomenology.
