The Muon g-2 Experiment at Fermilab is on track to measure the muon magnetic anomaly to better than 140 parts-per-billion (ppb), an unprecedented level of precision. The muon's magnetic anomaly is sensitivity to all sectors of the Standard Model (SM), and thus provides a stringent test of the SM's completeness. The Muon g-2 Collaboration published its most recent result last summer (August...
One of the future upgrade scenarios proposed for Jefferson Lab is the addition of a positron beam capabilities. Positron scattering from hadronic targets can provide new information that cannot be accessed from electron scattering alone. Asymmetries between electron- and positron-scattering can isolate interference effects, such as those between deeply virtual Compton scattering and the...
Two photon exchange is one possible explanation for the disparity in the proton form factor ratio when comparing results from Rosenbluth scattering and polarization transfer experiments. To measure the effect of two photon exchange alone we intend to compare the different scattering asymmetries for electrons and positrons scattering off a polarized proton target. The asymmetry difference in...
