The SuperBigBite Spectrometer and Measurements of Neutron Form Factors G^M_n and G^E_n Up to Q² = 13.6 (GeV/c)² in Experimental Hall A at Jefferson Lab

The Super BigBite Spectrometer (SBS) in Experimental Hall A at Jefferson Lab comprises multiple detector subsystems, enabling particle tracking and triggering in both of its electron and hadron arms. The SBS collaboration is using this new spectrometer to delve deeper into nucleon structure and QCD, with semi-inclusive measurements already made of the elastic neutron electromagnetic form factors G_Mⁿ and G_Eⁿ from liquid deuterium and polarized helium-3 targets (respectively). Plans are in place to measure the elastic proton electric form factor G_E^p, along with many other quantities of interest throughout the SBS program. SBS is uniquely equipped for these measurements in Jefferson Lab’s 12-GeV era, utilizing a high luminosity electron beam and covering a Q² range from 3 to 13.6 (GeV/c)². This is achieved through the simultaneous detection of elastically scattered nucleons and measurement of polarization transfer observables. A brief overview of nucleon form factors, the layout of the SBS spectrometer, and the measurement methodology employed to analyze the data will be presented in this talk.
