Recent Results From the Two Photon Exchange Experiment at CLAS

Recent results from experiments conducted at Thomas Jefferson National Accelerator Facility have shown a discrepancy in the measurement of the ratio of the Electric ($G_E$) and magnetic ($G_M$) form factors of the proton measured by Rosenbluth Separation and Polarization Transfer Methods. The real part of the Two Photon Exchange (TPE) amplitude in lepton-proton elastic scattering is expected to explain this discrepancy. The ratio of elastic positron-proton to electron-proton cross sections is the only way to access this real part. Measurements of the cross section ratio using a mixed electron-positron beam in CLAS at Jefferson Lab were made. In this talk I will present results from the 2006 TPE test run. The result will focus on two bin in $Q^2$ and $\epsilon$ ($0.4\ge Q^2\le1.0$, $0.3\ge \epsilon \le0.5$ and $0.4\ge Q^2 \le1.0$, $0.75\ge\epsilon\le0.92$).
