Abstract: The MOLLER experiment will measure the weak charge of the electron, $Q^e_W = 1 - 4\sin^2θ_W$, with a precision of 2.3% by measuring the parity-violating asymmetry in electron-electron (M\oller) scattering. This measurement will provide an ultra-precise measurement of the weak mixing angle, $\sin^2θ_W$, which is on par with the two most precise collider measurements at the Z$^0$-pole. The precision of the experiment, with a fractional accuracy in the determination of $\sin^2θ_W$ $\approx 0.1$%, makes it a probe of physics beyond the Standard Model with sensitivities to mass scales of new physics up to 7.5 TeV.
