1. Prompt neutrinos from atmospheric charm in the general-mass variable-flavor-number scheme / Benzke, M. ; Garzelli, M. ; Kniehl, B. ; Kramer, G. ; et al
We present predictions for the prompt-neutrino flux arising from the decay of charmed mesons and baryons produced by the interactions of high-energy cosmic rays in the Earth’s atmosphere, making use of a QCD approach on the basis of the general-mass variable-flavor-number scheme for the description of charm hadroproduction at NLO, complemented by a consistent set of fragmentation functions.

4. Counting the number of master integrals for sunrise diagrams via the Mellin-Barnes representation / Kalmykov, Mikhail ; Kniehl, Bernd
A number of irreducible master integrals for L -loop sunrise and bubble Feynman diagrams with generic values of masses and external momenta are explicitly evaluated via the Mellin-Barnes representation..

5. On the b -quark running mass in QCD and the SM / Bednyakov, A.V. ; Kniehl, B.A. ; Pikelner, A.F. ; Veretin, O.L.
We consider electroweak corrections to the relation between the running MS‾ mass mb of the b quark in the five-flavor QCD×QED effective theory and its counterpart in the Standard Model (SM). [...]

9. 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. [...]
