Leading-order QED radiative corrections to timelike Compton scattering on the proton

Matthias Heller, Niklas Keil, Marc Vanderhaeghen

We evaluate the leading-order QED radiative corrections to the timelike Compton scattering (TCS) process $\gamma p\to l^{-}{l}^{+}p$. We study these corrections in two energy regimes using…
