FPCP / Production of Lambda_b baryon and B0s mesons at LHCb

Heavy hadron production is a well suited benchmark process for understanding QCD. While the b-quark production properties can to be estimated within the perturbative QCD, the following fragmentation into a b-hadron is a non-perturbative process and cannot be calculated from the first principles. The understanding of the fragmentation functions and fractions thus relies solely on the experimental input. Recently, LHCb have taken a closer look at the properties of Lambda_b baryon and B_s meson production. The new results demonstrate that the b-quark fragmentation clearly depends on the kinematics of the produced hadrons, including the B_s production which so far has been less understood.
