abstract = {We study inclusive $Λ_{c}^±$-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 $c \to
Λ_{c}^±$ 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 $Λ_{c}^±$ production cross sections from
the LHC experimental collaborations is not resolved. The
ratio of data for $Λ_{c}^+$-baryon and D$^0$-meson
production seems to violate the universality of c-quark to
c-hadron fragmentation.},
