We review the present theoretical and empirical knowledge for α s, the fundamental
coupling underlying the interactions of quarks and gluons in Quantum Chromodynamics …

The conventional scale setting approach to fixed-order perturbative QCD (pQCD)
predictions is based on a guessed renormalization scale, usually taking as the one to …

A bstract We calculate all major differential distributions with stable top-quarks at the LHC.
The calculation covers the multi-TeV range that will be explored during LHC Run II and …

A valid prediction for a physical observable from quantum field theory should be
independent of the choice of renormalization scheme—this is the primary requirement of …

A bstract The problem of scheme and gauge dependence of the factorization property of the
renormalization group β-function in the SU (N c) QCD generalized Crewther relation (GCR) …

We compute the nonsinglet Adler D-function and the coefficient function for Bjorken
polarized sum rules SB jp at order O (α s 4) in an extended QCD model with arbitrary …

A bstract The three-loop Adler D-function for\(\mathcal {N}= 1\) SQCD in the\(\overline
{\mathrm {DR}}\) scheme is calculated starting from the three-loop result recently obtained …

A bstract We derive explicit expressions for the elements of the {β}-expansion for the
nonsinglet Adler D A-function and Bjorken polarized sum rules S Bjp in the N 4 LO using …

A bstract We discuss the {β}-expansion for renormalization group invariant quantities tracing
this expansion to the different contractions of the corresponding incomplete BPHZ R …

We consider a new form of analytical perturbation theory expansion in the massless SU (N
c) theory, for the nonsinglet part of the e+ e--annihilation to hadrons Adler function D ns and …
