Novel analysis for the energy-energy correlation in electron-positron annihilation in the perturbative domain
Zhu-Yu Ren, Sheng-Quan Wang, Jian-Ming Shen +4
The energy-energy correlation (EEC) in electron-positron annihilation plays a crucial role in precision tests of quantum chromodynamics (QCD) and measurements of the QCD coupling c…
A new method for estimating unknown one-order higher QCD corrections to the perturbative series using the linear regression through the origin
Zhi-Fei Wu, Xing-Gang Wu, Jiang Yan +2
It is generally believed that the QCD theory is the fundamental theory for strong interactions. Due to the asymptotic freedom at the short distances, after proper factorization, on…
Reviving the energy-dependent partonic structure of via two-pion distribution amplitudes
Shan Cheng, Ling-yun Dai, Jian-ming Shen +1
We present a novel framework for analyzing four-body semileptonic weak decays, performing the first high-twist analysis of the form factors usi…
Analysis of the Pion Electromagnetic Form Factor with Next-to-Next-to-Leading Order QCD Corrections
Sheng-Quan Wang, Zuo-Fen Liao, Jian-Ming Shen +5
NNLO QCD corrections for the pion electromagnetic form factor at large momentum transfer have been recently performed in [Phys. Rev. Lett. 132, 201901 (2024); Phys. Rev. Lett. 134,…
Analysis of up to Next-to-Next-to-Leading Order QCD Corrections
Wen-Yuan Li, Sheng-Quan Wang, Jian-Ming Shen +3
The rare exclusive decay of the Higgs boson is an important channel for measuring the Yukawa coupling of the charm quark. In this article, we analyze the process b…
A reanalysis of event shape distributions in electron-positron annihilation
Zhu-Yu Ren, Sheng-Quan Wang, Jian-Ming Shen +2
Theoretical calculations for event shape observables are often determined by using the conventional scale setting; i.e. the procedure defined by setting the renormalization scale t…
