Optimization of perturbation series in QCD for physical quantities using the renormalization group: necessary conditions and partial results
D. Kotlorz, S. V. Mikhailov
We explore approaches to numerically optimize a segment of the perturbative series for physical quantities using the QCD renormalization group. We apply these methods to the pertur…

Charge sum rules for quark fragmentation functions
D. Kotlorz, O. V. Teryaev
Charge sum rules for quark fragmentation functions are studied. The simultaneous implementation of the conservation of electric and baryon charges, strangeness and isospin symmetry…
