在ILC生产WWZ和ZZZ的NLO更正
NLO corrections to WWZ and ZZZ production at the ILC
摘要:
我们计算了ILC中三玻色子产生的全部单圈电弱修正(ZZZ和WWZ)。这对于理解标准模型规范四次耦合是很重要的,它可以作为研究自发对称性破缺机制的一个窗口。我们发现,即使减去了主导的QED修正,电弱修正仍然可以很大,特别是随着能量的增加。
英文摘要:
We calculate the full one-loop electroweak corrections to tri-boson production (ZZZ and WWZ) at the ILC. This is important to understand the Standard Model (SM) gauge quartic couplings which can be a window on the mechanism of spontaneous symmetry breaking. We find that even after subtracting the leading QED corrections, the electroweak corrections can still be large especially as the energy increases.
