Charged hadron fragmentation functions at high energy colliders

We update our extraction of parton-to-charged hadron fragmentation functions at next -to -leading order accuracy in quantum chromodynamics (QCD), focusing on the wealth of data collected at the Large Hadron Collider over the past decade. We obtain an accurate description of single -inclusive processes involving unidentified charged hadrons produced at different rapidities and transverse momenta in proton -proton collisions in a wide range of center -of -mass system energies between 0.9 and 13 TeV, along with measurements performed in proton -antiproton collisions at the Tevatron Collider in the past. Next -to -leading order estimates of charged hadron production rates agree best with data when the theoretical factorization scales are selected similar to those optimized for identified pions, kaons, and protons in a recent global QCD analysis.
