本文给出了正负电子湮灭中几种喷流算法的结果：考虑了正负电子湮灭中典型的排他顺序复合算法达勒姆、日内瓦、Jade-E 0和剑桥。此外，还研究了包容性射流算法。结果提供了包容性的顺序重组算法达勒姆，亚琛和反KT，以及红外安全锥算法SISCone。在微扰QCD中得到的结果是：双喷注速率为N_3LO，三喷注速率为NNLO，四喷注速率为NLO，五喷注速率为LO。
This article gives results on several jet algorithms in electron–positron annihilation: Considered are the exclusive sequential recombination algorithms Durham, Geneva, Jade-E0 and Cambridge, which are typically used in electron–positron annihilation. In addition also inclusive jet algorithms are studied. Results are provided for the inclusive sequential recombination algorithms Durham, Aachen and anti-kt, as well as the infrared-safe cone algorithm SISCone. The results are obtained in perturbative QCD and are N3LO for the two-jet rates, NNLO for the three-jet rates, NLO for the four-jet rates and LO for the five-jet rates.
