Description
We will discuss the inclusive high-pT charged particle production in proton-proton
and proton-antiproton collisions with a special emphasis on the recent LHC and
Tevatron measurements. 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
LHC and Tevatron 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.
