New Proton Form Factor Ratio Recoil Polarization Measurements in Hall C at JLab

The experimental determination of the proton elastic form factors has become a very active field since two experiments at JLab using the double-polarization technique revealed a stark discrepancy from the previous Rosenbluth data. In a next step, started in the fall of 2007, a new experiment in Hall C at JLab has pushed the Q2 limit from 5.6 to 8.54GeV2, with intermediate points at 5.2 and 6.8GeV2. The kinematics dependence of the form factor ratio at 2.5GeV2 has also been investigated. The current status of the data analysis and some preliminary results are reported.
