NNLO initial-state corrections to $e^{+}{e}^{-}\to {\mu }^{+}{\mu }^{-}\gamma$

Yizhou Fang, Sara Gündogdu, Sophie Kollatzsch +3

We present initial-state corrections to $e^{+}{e}^{-}\to {\mu }^{+}{\mu }^{-}\gamma$ at next-to-next-to-leading-order in QED for several experimentally motivated scenarios up to a few GeV. We include…
