Low-energy scattering of the and system
Jiang Yan, Xiong-Hui Cao, Meng-Lin Du +1
The paper studies low‑energy interactions between the charmonium state J/ψ and light pseudoscalar mesons (π and K) using dispersion‑relation techniques, extracting scattering lengt…
EEXICC: An event generator for doubly heavy baryon production at colliders
Hong-Tai Li, Xu-Chang Zheng, Xing-Gang Wu +2
We present EEXICC, a Monte Carlo event generator designed to simulate the production of doubly heavy baryons (, , and ) via annihilation. Based…
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…
Renormalization and Factorization Scale-Invariant Predictions for the Higgs Rare Decay via the Principle of Maximum Conformality
Qi-Sha Ran, Xing-Gang Wu, Jiang Yan +2
We investigate the \(J/Ï\) direct production mechanism in the rare exclusive Higgs decay \(H\to J/Ï+γ\) within nonrelativistic QCD (NRQCD), which provides a clean probe for extr…
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,…
Scale-invariant total decay width using the novel method of characteristic operator
Jiang Yan, Xing-Gang Wu, Jian-Ming Shen +2
In this paper, a novel method via using the characteristic operator~(CO) is proposed to extend the applicability of PMC, which is a theoretical genera…
