We compare the transverse-momentum () distribution of inclusive light-charged-particle production measured by the CDF Collaboration at the Fermilab Tevatron with the theoretical prediction evaluated at next-to-leading order in quantum chromodynamics using fragmentation functions recently determined through a global data fit. While in the lowerrange the data agree with the prediction within the theoretical error or slightly undershoot it, they significantly exceed it in the upperrange, by several orders of magnitude at the largest values of, potentially challenging the factorization theorem.
