Box integrals with fermion bubbles for low-energy measurements of the weak mixing angle

Nico Böttcher, Niklas Schwanemann, Stefan Weinzierl

The Moller experiment and the P2 experiment aim at measuring the weak mixing angle at low scales. The Moller experiment uses $e^{-}{e}^{-}\to e^{-}{e}^{-}$-scattering, the P2 experi…
