计算QCD中的四回路校正

Calculating Four-Loop Corrections in QCD

S. Moch, V. Magerya

摘要:

本文综述了量子色动力学中四圈微扰修正的研究现状,重点讨论了量子色动力学中的深非弹性散射和电子正电子湮没。的计算建立在参数减少循环和相空间积分到四个循环的顺序,使用计算机代数程序,如FORM,设计用于大规模计算。

英文摘要:

We review the current status of perturbative corrections in QCD at four loops for scattering processes with space- and time-like kinematics at colliders, with specific focus on deep-inelastic scattering and electron-positron annihilation. The calculations build on the parametric reduction of loop and phase space integrals up to four-loop order using computer algebra programs such as FORM, designed for large scale computations.
