I.A.Qattan

New extraction of the elastic scattering cross-section ratio Re+e- at high Q2

NUCLEAR REACTIONS 1H(e, e), (e+, e+), Q2=5.9-15.7 (GeV/c)2; deduced positron-proton to electron-proton elastic scattering s(E) ratio, hard two-photon-exchange (TPE) correction to σ. Two methods used for the extraction of σ ratio - Borisyuk-Kobushkin parametrization and analysis of combined unpolarized and polarized ep elastic scattering experimental data.
