Regularization Prescription for the Mixing Between Nonlocal Gluon and Quark Operators
Yao Ji, Zhuoyi Pang, Fei Yao +1
It is well-known that in the study of mixing between nonlocal gluon and quark bilinear operators there exists an ambiguity when relating coordinate space and momentum space results…

Two-Loop Renormalization-Group Evolution for the Nucleon Distribution Amplitude
Yong-Kang Huang, Yao Ji, Bo-Xuan Shi +1
We determine for the first time the two-loop renormalization-group (RG) equation for the nucleon light-cone distribution amplitude, which constitutes the last missing ingredient fo…

Extracting Meson Distribution Amplitudes from Nonlocal Euclidean Correlations at Next-to-Next-to-Leading Order
Yao Ji, Fei Yao, Jian-Hui Zhang
We present the first complete result for the next-to-next-to-leading order (NNLO) hard matching kernel indispensable for a precision extraction of light meson distribution amplitud…
