P2 - The weak charge of the proton — •Dominik Becker — Institut für Kernphysik, Mainz

Since early 2012, a new high precision measurement of the proton weak charge is being prepared in Mainz. It is our goal to determine the electroweak mixing angle sin²(θ_W) to a relative precision of 0.15 %, which can be achieved by measuring the proton weak charge to a relative uncertainty of 1.9 % through the parity-violating asymmetry in elastic electron-proton-scattering at low momentum transfer. We will present studies of the achievable precision in the determination of sin²(θ_W) within P2. Furthermore, we are going to show results of GEANT4 simulations, which are being done to explore the future experimental setup.
