论文摘要
我们使用半数字方法根据奇异和常规运动点和数值匹配的主积分的串联扩展来报告我们最近对大规模夸克形式的计算。这些方法允许涵盖具有至少七个重要数字精度的虚拟性$ s $的负值和正值的整个运动学范围。
We report on our recent calculation of massive quark form factors using a semi-numerical approach based on series expansions of the master integrals around singular and regular kinematic points and numerical matching. The methods allows to cover the whole kinematic range of negative and positive values of the virtuality $s$ with at least seven significant digits accuracy.
