Next-to-next-to-leading order $\text{QCD}\otimes \text{EW}$ corrections to $Z$-boson pair production at electron-positron colliders

Zhe Li, Ren-You Zhang, Shu-Xiang Li +5

We present a comprehensive analytic calculation of the next-to-next-to-leading order $\text{QCD}\otimes \text{EW}$ corrections to $Z$-boson pair production at electron-positron co…
