Three-loop QCD+QED corrections to on-shell quark renormalization
Long Chen, Hong-Yang Han, Zhe Li +1
We present the three-loop QCD+QED mixed corrections to the on-shell quark mass and wave-function renormalization constants through orders with . We f…
Total Gluon Helicity Contribution to the Proton Spin from Lattice QCD
Dian-Jun Zhao, Long Chen, Hongxin Dong +8
We report a state-of-the-art lattice QCD calculation of the total gluon helicity contribution to the proton spin, . The calculation is done on ensembles with three different la…
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…
Trace-anomaly-subtracted -mass for Heavy Quarks and Matching from Lattice QCD
Long Chen, Cong Zhao
We demonstrate that the leading IR-renormalon divergence in the perturbative pole mass of a massive quark resides entirely in the contribution from the trace anomaly of the energy-…
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…
Renormalization of the pseudoscalar operator at four loops in QCD
Long Chen, Michał Czakon, Marco Niggetiedt
We present the renormalization constant of the pseudoscalar operator defined with a non-anticommuting in dimensional regularization up to four-loop order in perturbative Quan…
