Low Q^2 measurements of the proton form factor ratio $mu_p G_E / G_M$
We present an updated extraction of the proton electromagnetic form factor ratio, {mu}{sub p}G{sub E}/G{sub M}, at low Q{sup 2}. The form factors are sensitive to the spatial distribution of the proton, and precise measurements can be used to constrain models of the proton. An improved selection of the elastic events and reduced background contributions yielded a small systematic reduction in the ratio {mu}{sub p}G{sub E}/G{sub M} compared to the original analysis.
Measurement of the Proton Elastic Form Factor Ratio at Low Q2
A new measurement of the proton elastic form factor ratio μpGE/GM in the range of Q2 = 0.3–0.7 (GeV/c)2 was made at Jefferson lab (JLab) Hall A using recoil polarimetry. With unprecedented (∼1%) precision, the new data show that the proton form factor ratio strongly deviates from unity in this low momentum transfer region, indicating a significant difference between the proton charge and magnetic distribution at large length scale. The new result is a few percent lower than previous world polarization data. The updated global fit indicates a 2% decrease in GE and 1% increase in GM in this low Q2 region.
