Title Measurements of the Neutron Magnetic Form Factor and the Two-Photon Exchange Contribution to the Electron-Neutron Elastic Scattering Cross Section
Abstract The Super BigBite Spectrometer (SBS) program in Experimental Hall A of Jefferson Lab is a series of high-precision, large ¿2 , electromagnetic form factor experiments. GMn and nTPE were the first two experiments of the SBS program and ran from Oc¿tober 2021 through February 2022. Both experiments detect neutron-tagged ¿(¿, ¿'¿) and proton-tagged ¿(¿, ¿'¿) quasi-elastic electrons scattering from a deuterium tar¿get. The GMn experiment is a measurement of the magnetic form factor of the neutron, ¿¿ ¿, via the ratio method over a ¿2 range of 3.5 to 13.5 (GeV/c)2 . The nTPE experiment ran in-parallel with the GMn experiment and shared an overlap¿ping kinematic point with GMn. nTPE extends the GMn experiment to assess the differences between Rosenbluth Slop and the single-photon exchange approximation. The nTPE experiment had two kinematic settings corresponding to different electron scatting angles at a fixed ¿2 of 4.5 (GeV/c)¿ . Comparisons of nucleon form fact
