1. Charged hadron fragmentation functions from collider data / Bertone, V. ; Hartland, N. P. ; Nocera, E. R. ; Rojo, J. ; et al
We present NNFF1.1h, a new determination of unidentified charged-hadron fragmentation functions (FFs) and their uncertainties. [...]

2. Impact of low- x resummation on QCD analysis of HERA data / Abdolmaleki, Hamed ; Bertone, Valerio ; Britzger, Daniel ; Camarda, Stefano ; et al
Fits to the final combined HERA deep-inelastic scattering cross-section data within the conventional DGLAP framework of QCD have shown some tension at low x and low Q2 . [...]

3. Parton distributions with small- x resummation: evidence for BFKL dynamics in HERA data / Ball, Richard D. ; Bertone, Valerio ; Bonvini, Marco ; Marzani, Simone ; et al
We present a determination of the parton distribution functions of the proton in which NLO and NNLO fixed-order calculations are supplemented by NLL x small- x resummation. [...]

4. Heavy-flavor parton distributions without heavy-flavor matching prescriptions / Bertone, Valerio ; Glazov, Alexandre ; Mitov, Alexander ; Papanastasiou, Andrew ; et al
We show that the well-known obstacle for working with the zero-mass variable flavor number scheme, namely, the omission of O 1 $$ \mathcal{O}(1) $$ mass power corrections close to the conventional heavy flavor matching point (HFMP) μ b = m , can be easily overcome. [...]

5. 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. [...]

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. [...]
