abstract = {We study inclusive $\Lambda_c^{\pm}$-baryon production in
$pp$ collisions in the general-mass variable-flavor number
scheme and compare with data from the LHCb, ALICE and CMS
collaborations. We perform a new fit of the $c \to
\Lambda_c^+$ fragmentation function combining $e^+e^-$ data
from OPAL and Belle. The agreement with LHC data is slightly
worse compared with a calculation using an older
fragmentation function, and the tension between different
determinations of $\Lambda_c^{\pm}$ production cross
sections from the LHC experimental collaborations is not
resolved. The ratio of data for $\Lambda_c^+$-baryon and
$D^0$-meson production seems to violate the universality of
$c$-charm quark to $c$-hadron fragmentation.},
