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

In this work, I present new extractions of the positron-proton to electron-proton elastic scattering cross-sections ratio Re+e-(ϵ,Q2) at high Q2 covering the range 5.994 ≤Q2≤ 15.721(GeV/c)2 following two approaches. I also present an estimate of the size of the hard-TPE correction to σR at high Q2, along with the uncertainties associated with the model dependence of the extractions. My results on Re+e-, based on the two approaches used, are in generally very good quantitative agreement with each other. Because world data on the ratio Re+e- are only available for Q2<2.1(GeV/c)2, below where the discrepancy on the proton's form factors ratio μpRp=μpGE/GM is significant, my results provide new predictions for Re+e-(ϵ,Q2) at such a high-Q2 range, which is yet to be measured.
