Non-perturbative ultraviolet fate of quasi-stable (temporarily free) massive non-Abelian gauge theories
All-orders factorization for semi-inclusive QCD processes with identified hadrons: from e+e- annihilation to purely hadronic pp to pi + X (the open problem beyond Georgi-Politzer)
Scale setting for asymptotic-freedom predictions: nonperturbative inputs, singlet mixing, and the spacelike-timelike continuation
