Controlling quark mass determinations non-perturbatively in three-flavour QCD
EPJ Web of Conferences, 2017 The determination of quark masses from lattice QCD simulations requires a non-perturbative renormalization procedure and subsequent scale evolution to high energies, where a conversion to the commonly used MS¯$\overline {{\rm{MS}}} $ scheme can be safely

Perturbative QCD in a non-perturbative vacuum
Physics Letters B, 1981 Abstract We propose a procedure for interpreting the presence of a background gluon field in the context of perturbative QCD. We expect our method to be useful when non-perturbative effects are significant but not completely dominant.

Up- and down-quark masses from QCD sum rules
Journal of High Energy Physics, 2019 The QCD up- and down-quark masses are determined from an optimized QCD Finite Energy Sum Rule (FESR) involving the correlator of axial-vector current divergences.

Pomeron interaction in the perturbative QCD
EPJ Web of Conferences, 2016 Formation of the triple pomeron vertices in processes P→PP→PPP and PP→P→PP is studied in the BFKL-Bartels approach. It is demonstarted that successive splittings of the pomeron indeed generate the standard triple pomeron vertex in agreement with the ...

The Revival of Kaon Flavour Physics
EPJ Web of Conferences, 2016 After years of silence we should witness in the rest of this decade and in the next decade the revival of kaon flavour physics. This is not only because of the crucial measurements of the branching ratios for the rare decays K+ → π+vv̄ and KL → π0vv̄ by ...

The transverse momentum spectrum of weak gauge bosons at N$${}^3$$ 3 LL + NNLO
European Physical Journal C: Particles and Fields, 2019 We present accurate QCD predictions for the transverse momentum ($$p_\perp $$ p⊥ ) spectrum of electroweak gauge bosons at the LHC for $$13~\mathrm {TeV} $$ 13TeV collisions, based on a consistent combination of a NNLO calculation at large $$p_\perp $$ p⊥

Five-loop contributions to low-N non-singlet anomalous dimensions in QCD
Physics Letters B, 2019 We present the first calculations of next-to-next-to-next-to-next-to-leading order (N4LO) contributions to anomalous dimensions of spin-N twist-2 operators in perturbative QCD.
