Spin correlations and quantum entanglement in $I^^{3} I^^{3} \to t t ˉ$ at polarized photon colliders with NLO QCD corrections

Jun Jiang, Zong-Guo Si, Han Zhang +1

We study spin correlations and quantum entanglement in the process $I^^{3} I^^{3} \to t t ˉ$ with the photons coming from Compton backscattered laser beam. We present predictions for the c…

Probing the electromagnetic dipole moment of the $I ¨ $ lepton in the $e^+e^- \to Î³^*/Z \to Ï^+ Ï^-$ reaction

Peng-Cheng Lu, Zong-Guo Si, Han Zhang

High-precision measurements of the lepton's electromagnetic dipole moments provide a powerful probe for testing the Standard Model. A non-zero value of the $I ¨ $ lepton's electric(w…

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 $I^^{3} I^^{3} \to I ¨ ^{+} I ¨ ^{-}$ process in Pb-Pb ultraperipheral collision (UPC). We find that the EW correction $Î…
