Sensitivity to two photon exchange in time-like form factor measurements at PANDA

Abstract : At PANDA (FAIR) proton time-like form factors measurements are foreseen. In this work, following detailed simulations, we study the sensitivity to possible two photon exchange contribution in the annihilation process $\bar p+p\to e^++e^-$, through the induced asymmetry in the angular distribution. Asymmetries related to systematic errors are also investigated.
