On-shell Matrix Elements of the EMT Trace in Gauge Theories and Heavy Quark Masses
Long Chen, Zhe Li, Marco Niggetiedt
We present a novel diagrammatic proof of the identity between the forward matrix element of the energy-momentum-tensor (EMT) trace operator over a single particle's on-shell state…

Three-loop QCD Mass Relation between the and Symmetric-momentum Subtraction Scheme Away from the Chiral Limit
Long Chen, Marco Niggetiedt
The perturbative result for the quark-mass conversion factor between the and regularization-independent symmetric-momentum subtraction scheme (RI/SMOM) awa…
