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.

2. 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. [...]

4. A critical appraisal and evaluation of modern PDFs / Accardi, A. ; Alekhin, S. ; Blümlein, J. ; Garzelli, M. V. ; et al
We review the present status of the determination of parton distribution functions (PDFs) in the light of the precision requirements for the LHC in Run 2 and other future hadron colliders. [...]

6. Impact of heavy-flavour production cross sections measured by the LHCb experiment on parton distribution functions at low x / Zenaiev, O. ; Geiser, A. ; Lipka, K. ; Blümlein, J. ; et al
The impact of recent measurements of heavy-flavour production in deep inelastic ep scattering and in pp collisions on parton distribution functions is studied in a QCD analysis in the fixed-flavour number scheme at next-to-leading order. [...]
