Description
MESA, the Mainz Energy-Recovering Superconducting Accelerator,
will offer the possibility to measure the scattering of polarized
electrons off protons at small energies (E=155 MeV) with very high
precision.The parity-violating polarization asymmetry is determined
by the weak charge of the proton and offers the possibility to measure
the weak mixing angle with a relative precision of 0.13 %, competitive
with past high-energy and upcoming LHC measurements. I will discuss
challenges and the status of calculations of theoretical predictions for
this measurement.
