1. Running of the charm-quark mass from HERA deep-inelastic scattering data / Gizhko, A. ; Geiser, A. ; Moch, S. ; Abt, I. ; et al
Combined HERA data on charm production in deep-inelastic scattering have previously been used to determine the charm-quark running mass mc(mc) in the MS‾ renormalisation scheme. [...]

8. Inclusive B -meson production at small pT in the general-mass variable-flavor-number scheme / Kniehl, B. A. ; Kramer, G. ; Schienbein, I. ; Spiesberger, H.
We calculate the cross section for the inclusive production of B mesons in pp and pp¯ collisions at next-to-leading order in the general-mass variable-flavor-number scheme and show that a suitable choice of factorization scales leads to a smooth transition to the fixed-flavor-number scheme. [...]
