Description

The P2 collaboration prepares a precise determination of the weak mixing angle at low energy at the upcoming MESA accelerator in Mainz. The projected relativce accuracy is 0.15% which is comparable to the existing measurements at the Z-pole. This accuracy will allow for a test of the Standard Model up to a mass scale of 50 TeV. The experimental method, the measurement of the parity violating asymmetry in the scattering of polarized electrons off unpolarized protons, will be discussed along with the challenging experimental techniques associated with such a precision goal. The status of the project will be reported.
