abstract
We discuss the constraints on quark and gluon energy-momentum tensors in QCD that follow from the requirement of Renormalisation-Group invariance of the traces of these operators. Our study covers the most general form of the latter traces, while the energy-momentum tensors themselves are only subjected to very mild constraints. We derive Renormalisation-Group equations for the two finite independent functions of the strong coupling constant and renormalisation scale of minimal subtraction which completely define the energy-momentum tensors. We demonstrate that previously proposed definitions of the renormalized quark and gluon energy-momentum tensors are special cases of our results assuming no explicit dependence on the renormalisation scale. Finally, we present $\overline{\mathrm{MS}}$-renormalised quark and gluon energy-momentum tensors at four-loop order.

Chromoelectric and chromomagnetic matching to scalar and spin-two nucleon structure
A consistent matching framework shows the chromomagnetic-to-chromoelectric ratio rescales the gluonic spin-two/scalar response by (1+rho)/(1-rho) in aligned quarkonium-nucleon scattering.

Misconceptions About the Physics of the QCD Trace Anomaly from Renormalization in a Reducible Basis
This paper critiques reducible-basis renormalization of the QCD trace anomaly, arguing it introduces unphysical scheme dependence and that the standard whole-anomaly decomposition is the only symmetry-allowed choice.
