NLO EW corrections to tau pair production via photon fusion in Pb-Pb ultraperipheral collision

Jun Jiang, Peng-Cheng Lu, Zong-Guo Si +2

We study the next-to-leading order (NLO) electroweak (EW) corrections to the $\gamma \gamma \to {\tau }^{+}{\tau }^{-}$ process in Pb-Pb ultraperipheral collision (UPC). We find that the EW correction $δσ_{\…
