AI 中文摘要
我展示了QCD中四圈大质量尖点反常维数的新结果。我将部分精确和推测的解析表达式与基于尖点反常维数渐近行为的近似相结合，以产生最新的估计。与先前的近似结果进行了详细比较，突出了计算方法鲁棒性。
英文摘要
I present new results for the massive cusp anomalous dimension at four loops in QCD. I combine partial exact and conjectured analytical expressions with an approximation that is based on the asymptotic behavior of the cusp anomalous dimension to produce the newest estimates. Detailed comparisons are made with previous approximate results that highlight the robustness of the calculational approach.
