Solenoid spectrometer studies for the P2 experiment at MESA — •Dominik Becker1, Kathrin Gerz1, Sebastian Baunack1, Thomas Jennewein1, Krishna S. Kumar3, Frank E. Maas1,2, Razvan D. Bucoveanu4, and Hubert Spiesberger4 for the P2 collaboration — 1PRISMA Cluster of Excellence and Institute of Nuclear Physics, Johannes Gutenberg University, Mainz, Germany — 2Helmholtz Institue Mainz, Germany — 3Department of Physics and Astronomy, Stony Brook University, Stony Brook, USA — 4PRISMA Cluster of Excellence and Institute of Physics, Johannes Gutenberg University, Mainz, Germany

The goal of Project P2 is to determine the electroweak mixing angle sin2W) to a precision of 0.15 % at low momentum transfer (Q2 = 0.004 GeV2/c2). The experiment will be performed at the future MESA accelerator facility in Mainz. The experimental method comprises a measurement of the proton’s weak charge QWp to a relative uncertainty of 1.9 % via the parity violating asymmetry in elastic electron-proton scattering. In the talk, the experimental method as well as the achievable precision in the determination of the electroweak mixing angle will be presented. Furthermore, results of Geant4 simulations which were carried out to study a possible experimental setup will be shown.
