Query: LHC data challenges the contemporary parton-to-hadron fragmentation
  functions   We discuss the inclusive high-pT charged-particle production in proton-proton
collisions at the LHC. The experimental data are compared to the NLO
perturbative QCD calculations employing various sets of parton-to-hadron
fragmentation functions. Most of the theoretical predictions are found to
disastrously overpredict the measured cross sections, even if the scale
variations and PDF errors are accounted for. The problem appears to arise from
the presently too hard gluon-to-hadron fragmentation functions.
