We study inclusive Λ AE 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 → Λ þ c fragmentation function combining e þ 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 AE c production cross sections from the LHCdoi:10.1103/physrevd.101.114021 fatcat:v6iii2b56vcvxh6rrvv6odccei
