    abstract = "Recent p(T)-integrated cross-section measurements of the ground-state
charm mesons and baryons, D-0, D+, D-s(+), Lambda(+)(c), and Xi(0)(c)
are used to evaluate the charm fragmentation fractions and production
cross section per unit of rapidity at midrapidity (vertical bar y
vertical bar < 0.5), in pp collisions at root s = 5.02 TeV at the LHC.
The latter is d sigma(c<(c)over) (bar>)/dy vertical bar(vertical bar y
vertical bar<0.5) = 1165 +/- 44(stat)(-101)(+131) (syst) mu b. These
measurements were obtained for the first time in hadronic collisions at
the LHC, including the charm baryon states, recently measured by ALICE
at midrapidity. The charm fragmentation fractions differ significantly
from the values measured in e(+)e(-) and ep collisions, providing
evidence of the dependence of the parton-to-hadron fragmentation
fractions on the collision system, indicating that the assumption of
their universality is not supported by the measured cross sections. An
increase of a factor of about 3.3 for the fragmentation fraction for the
Lambda(+)(c) with a significance of 5 sigma between the values obtained
in pp collisions and those obtained in e(+)e(-) (ep) collisions is
reported. The fragmentation fraction for the Xi(0)(c) was obtained for
the first time in any collision system. The measured fragmentation
fractions were used to update the c (c) over bar cross sections per unit
of rapidity at vertical bar y vertical bar < 0.5 at root s = 2.76 and 7
TeV, which are about 40% higher than the previously published results.
The data were compared with perturbative-QCD calculations and lie at the
upper edge of the theoretical bands."
