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 ...

Radiative B decay spectrum: DGE at NNLO.
, 2007 We compute the differential ¯B → Xsγ decay width in the Standard Model as a function of the photon energy using Dressed Gluon Exponentiation (DGE).

Novel approaches to perturbative scattering amplitudes in gauge theory and gravity
, 2009 PhDScattering amplitudes of massless quanta play a crucial role in the calculation of cross sections for multi-jet production at hadron colliders. The framework provided by perturbative quantum field theory, based on Feynman diagrams, does not capture ...

Foundations of perturbative QCD
, 2011 The most non-trivial of the established microscopic theories of physics is QCD: the theory of the strong interaction. A critical link between theory and experiment is provided by the methods of perturbative QCD, notably the well-known factorization ...

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 ...

Perturbation theory of non-perturbative QCD
, 2015 Perturbation theory is shown to be working in the IR limit of pure SU(3) Yang-Mills theory in Landau gauge by an unconventional setting of the perturbative expansion. A dynamical mass is predicted for the gluon and the lattice data are reproduced fairly well by a second-order expansion, without any free parameter.
