Decoherence as a Detector-Resolution Flow
Yao Ji, Yuqi Wang
We consider the QED final-state radiation modeled by , including its finite-temperature generalization, as an open quantum system, and study the evolution of th…
Generalized parton distributions: Theory meets experiment
Yuxun Guo, Xiangdong Ji, Yao Ji +1
Over the past three decades, generalized parton distributions (GPDs) have emerged as one of the most active and important areas of research in nucleon structure and quantum chromod…
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…
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…
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…
Next-to-Next-to-Leading-Order QCD Prediction for the Pion Form Factor
Yao Ji, Bo-Xuan Shi, Jian Wang +3
We accomplish for the first time the two-loop computation of the leading-twist contribution to the pion electromagnetic form factor by employing the effective field theory formalis…
