Radiative correction to the charge asymmetry in $e^{+} e^{-} \to I^¼^{+} I^¼^{-}$ process

Roman E. Gerasimov, Petr A. Krachkov, Roman N. Lee

We calculate the next-to-next-to-leading order (NNLO) QED corrections to the $C$ -odd part of the differential cross section of the $e^{+} e^{-} \to I^¼^{+} I^¼^{-}$ process. This part contribute…

Electron-positron annihilation into heavy leptons at two loops

Roman E. Gerasimov, Petr A. Krachkov, Roman N. Lee

We calculate the NNLO QED corrections to the $C$ -even part of differential cross section of $e^{+} e^{-} \to I^¼^{+} I^¼^{-}$ process. We neglect power corrections in the electron mass and obt…
