Soft-photon radiative corrections to the $e^{-} p \to e^{-} p l^{-} l^{+}$ process

Matthias Heller, Niklas Keil, Marc Vanderhaeghen

We calculate the leading-order QED radiative corrections to the process $e^{-} p \to e^{-} p l^{-} l^{+}$ in the soft-photon approximation, in two different energy regimes which ar…

Planar two-loop integrals for $μ e$ scattering in QED with finite lepton masses

Matthias Heller

We present analytic results for one of two types of planar QED two-loop integrals for $μ e$ scattering including finite lepton masses. No approximations are made, such that the resu…

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 $γ p \to l^{-} l^{+} p$ . We study these corrections in two energy regimes using…

Mixed QCD-EW two-loop corrections to Drell-Yan production

Matthias Heller, Andreas von Manteuffel, Robert M. Schabinger +1

The Drell-Yan production of charged lepton pairs is one of the key processes measured at hadron colliders. The QCD corrections to the cross section are known to order $α_{s}^{2}$ and e…

Leading order corrections to the Bethe-Heitler process in the $γ p \to l^{+} l^{-} p$ reaction

Matthias Heller, Oleksandr Tomalak, Marc Vanderhaeghen +1

The ratio of di-lepton production cross sections on a proton, using the $γ p \to l^{+} l^{-} p$ process, above and below di-muon production threshold allows to extract the effect…

Soft-photon corrections to the Bethe-Heitler process in the $γ p \to l^{+} l^{-} p$ reaction

Matthias Heller, Oleksandr Tomalak, Marc Vanderhaeghen

We report on the calculation of first-order QED corrections for the $γ p \to l^{+} l^{-} p^{'}$ process. An upcoming experiment at MAMI (Mainz) aims to compare the cross secti…
