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 ...

Phase Transition Critical Flavor Number of QCD [PDF]
arXiv, 2005 We present an entirely perturbative QCD determination of the critical phase transition flavor number $N^{cr}_{f}$ of QCD. The results obtained are compared with various determinations of $N^{cr}_{f}$ by non-pertrubative methods, including lattice QCD.

Multiparticle production and perturbative QCD [PDF]
Surveys in High Energy Physics, 2001 The perturbative quantum chromodynamics (QCD) is quite successful in the description of main features of multiparticle production processes. Ten most appealing characteristics are described in this brief review talk and compared with QCD predictions. The general perturbative QCD approach is demonstrated and its problems are discussed.

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 ...

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.

Journal of High Energy Physics, 2019 Starting from a factorization theorem in effective field theory, we present resummed results for two non-global observables: the invariant-mass distribution of jets and the energy distribution outside jets.

Operator Product Expansion in QCD Is Not Consistent With Quantum Field Theory For Gluon Distribution Function [PDF]
arXiv, 2018 Since the operator product expansion (OPE) is applicable at short distance the OPE in QCD does not solve the long distance confinement problem involving hadron in QCD where the non-perturbative QCD is applicable. In this paper we show that the gauge invariant definition of the non-perturbative gluon distribution function inside the hadron consistent ...
