abstract
In this paper the formulae are collected which are needed for the computation of the strong coupling constant and quark masses at different energy scales and for different number of active flavours. All equations contain the state-of-the-art QCD corrections up to three- and sometimes even four-loop order. For the practical implementation {\tt Mathematica} is used and a package containing useful procedures is provided.

A phenomenological 2-to-3 framework is constructed for exclusive boson electroproduction that matches flux-factorized predictions near Q^{2}=0 while capturing finite-Q^{2} effects at larger virtualities.
Using recent four-body quark model wave functions and NRQCD, the authors compute two-photon couplings and UPC cross sections for fully charmed tetraquarks, showing resonant terms exceed continuum in J/ψJ/ψ but not in γγ channels.
Sequence transformations applied to the fixed-order QCD series for hadronic tau decays produce estimates c5,1 = 298 ± 15, c6,1 = 3431 ± 256, c7,1 = 2.29 ± 0.29 × 10^4 and a predicted δ^(0)_FOPT = 0.2119 ± 0.0040.
Phenomenological constraints on complex Wilson coefficients in b→cūq transitions from branching fraction tensions, yielding predictions for ACP, γ, and mixing observables under color-singlet and color-rearranged scenarios.

Two photon decay width of the fully charmed tetraquarks: revisiting prospects for ultraperipheral collisions
Using recent four-body quark model wave functions and NRQCD, the authors compute two-photon couplings and UPC cross sections for fully charmed tetraquarks, showing resonant terms exceed continuum in J/ψJ/ψ but not in γγ channels.
