| Title | The Q_Weak^p Experiment: A Search For Physics Beyond The Standard Model Via A Measurement Of The Proton's Weak Charge | ||||
| Abstract | The Qweak collaboration is currently preparing a measurement of the proton's weak charge QWp = (1¿4 sin2thetaW) at the Thomas Jefferson National Accelerator Facility (TJNAF). The experiment has been designed to produce a 4.1% measurement of the weak charge, via a 2.5% measurement of the parity violating asymmetry in the number of elastically scattered 1 GeV electrons from protons, at forward angles. At the proposed precision, the experiment would produce a 0.3% measurement of the weak mixing angle at a momentum transfer of [approximate] = 16 GeV, making it the most precise stand alone measurement of the weak mixing angle at low momentum transfer. In combination with other parity measurements, Qweak will also provide a high precision determination of the weak charges of the up and down quarks. Our proposed measurement of QWp will be performed with significantly smaller statistical and systematic errors than existing low Q2 data.
