1. Impact of the heavy-quark matching scales in PDF fits / ; Bertone, V. ; Britzger, D. ; Camarda, S. ; et al
We investigate the impact of displaced heavy-quark matching scales in a global fit. [...]

2. Determination of the strong coupling constant αs(mZ) in next-to-next-to-leading order QCD using H1 jet cross section measurements / Andreev, V. ; Baghdasaryan, A. ; Begzsuren, K. ; Belousov, A. ; et al
The strong coupling constant αs is determined from inclusive jet and dijet cross sections in neutral-current deep-inelastic ep scattering (DIS) measured at HERA by the H1 collaboration using next-to-next-to-leading order (NNLO) QCD predictions. [...]

3. Parton distributions from high-precision collider data / Ball, Richard D. ; Bertone, Valerio ; Carrazza, Stefano ; Debbio, Luigi Del ; et al
We present a new set of parton distributions, NNPDF3.1, which updates NNPDF3.0, the first global set of PDFs determined using a methodology validated by a closure test. [...]

4. A determination of the fragmentation functions of pions, kaons, and protons with faithful uncertainties / Bertone, Valerio ; Carrazza, Stefano ; Hartland, Nathan P. ; Nocera, Emanuele R. ; et al
We present NNFF1.0, a new determination of the fragmentation functions (FFs) of charged pions, charged kaons, and protons/antiprotons from an analysis of single-inclusive hadron production data in electron–positron annihilation. [...]

5. A determination of the charm content of the proton / Ball, Richard D. ; Bertone, Valerio ; Bonvini, Marco ; Carrazza, Stefano ; et al
We present an unbiased determination of the charm content of the proton, in which the charm parton distribution function (PDF) is parametrized on the same footing as the light quarks and the gluon in a global PDF analysis. [...]

7. Intrinsic charm in a matched general-mass scheme / Ball, Richard D. ; Bertone, Valerio ; Bonvini, Marco ; Forte, Stefano ; et al
The FONLL general-mass variable-flavour number scheme provides a framework for the matching of a calculation in which a heavy quark is treated as a massless parton to one in which the mass dependence is retained throughout. [...]

8. On the impact of lepton PDFs / Bertone, Valerio ; Carrazza, Stefano ; Pagani, Davide ; Zaro, Marco

9. Parton distributions with threshold resummation / Bonvini, Marco ; Marzani, Simone ; Rojo, Juan ; Rottoli, Luca ; et al
We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNLL accuracy respectively, suitable for use in conjunction with any QCD calculation in which threshold resummation is included at the level of partonic cross sections.
