The Q-weak experiment is currently in the process of taking run two physics data.

Qweak is a precision measurement of the proton's weak charge at very low Q² using parity violating electron scattering off of the proton. (Q_PW = 1 - 4sin²Θ_w) A 2200 hour measurement of the parity violating asymmetry in elastic ep scattering at Q²=0.03 (GeV/c)² employing 180 μA of 85% polarized beam on a 35 cm liquid Hydrogen target will determine the proton's weak charge with approximately 4% combined statistical and systematic errors. A deviation from the weak mixing angle as currently theoretically predicted is an indication of new physics and will allow for an extension of the standard model.More information on the experiment may be found in this paper by experimental spokesman Roger Carlini.

Hall C is a user-driven physics hall which specializes in the following:

• Hypernuclear Spectroscopy (Inserting hyperons (particles with a strange quark content) into the nucleus and observing the resultant "hypernuclear" atoms. These tend to be Lambda(Λ) particles, being the lightest hyperons.)
• Investigating the Strange content of the Proton
• Observing transitions of both Quarks and Hadrons via spectroscopy.
• Extrapolating form factors for simple quark systems
