Abstract: The Standard Model of Particle Physics is currently the best description of fundamental particles and their interaction. To test the Standard Model we perform precise measurement of quantities that can be calculated very accurately. In the Qweak experiment at Jefferson Lab in Virginia, accelerated electrons were scattered off the protons inside a liquid hydrogen target cell to measure (for the first time) the weak charge of the proton. Analogous to its electric charge, the weak charge describes how strongly the proton interacts through the weak force. We currently find a value in agreement with the Standard Model calculations, but we have 25 times more data to analyze. The projected precision for the full data set will allow us to confirm or rule out certain theories for new physical processes at the TeV scale.
