Electron-proton elastic scattering at high momentum transfers

We report preliminary values of electron-proton elastic scattering measurements at the Stanford Linear Accelerator Center (SLAC) carried out at squared four-momentum transfers q^2 from 0.7 to 25.0 (GeV/c)^2. In the newly accessible region of q^2 above 10 (GeV/c)^2, the principal feature is the continued decrease of the magnetic form factor approximately as 1/q^4.
