| الوصف: | International audience ; We study inclusive Λc±-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→Λc+ 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 Λc± production cross sections from the LHC experimental collaborations is not resolved. The ratio of data for Λc+-baryon and D0-meson production seems to violate the universality of c-quark to c-hadron fragmentation. |
