Description
Identified hadron production in association with an electroweak gauge boson provides a powerful probe of QCD dynamics and hadron fragmentation in proton-proton collisions. We present next-to-next-to-leading-order (NNLO) QCD predictions for the associated production of a neutral electroweak gauge boson and an identified hadron at high energy colliders. The calculation employs the antenna subtraction formalism, consistently accounting for fragmentation contributions at NNLO. Phenomenological predictions are presented for fragmentation-sensitive observables, and the impact of the NNLO corrections for the perturbative convergence and theoretical precision of the predictions is investigated by comparing those with experimental data.
