One-loop matching of QCD currents to power-suppressed two-jet operators
Martin Beneke, Aleksey V. Rusov, Michel Stillger
We compute the matching of QCD quark-antiquark currents onto the set of the two-particle and three-particle two-jet operators in soft-collinear effective theory (SCET) at next-to-l…

Gradient-flowed operator product expansion without IR renormalons
Martin Beneke, Hiromasa Takaura
A long-standing problem concerns the question how to consistently combine perturbative expansions in QCD with power corrections in the context of the operator product expansion (OP…
