Compton Scattering Total Cross Section at Next-to-Next-to-Leading Order and Resummation of Leading Logarithms
Hai Tao Li, Yan-Qing Ma, Cheng-Tai Tan +2
Compton scattering is a fundamental process in QED with broad applications, yet its theoretical description at high energies is challenged by substantial next-to-leading order (NLO…

Analytical two-loop amplitudes of at factories
Xiang Chen, Xin Guan, Chuan-Qi He +3
In double charmonium production, a long-standing challenge is that the theoretical predictions are not consistent with the measurements at B factories. Within the NRQCD framework,…
