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…

Multiple polylogarithms with algebraic arguments and the two-loop EW-QCD Drell-Yan master integrals

Matthias Heller, Andreas von Manteuffel, Robert M. Schabinger

We consider Feynman integrals with algebraic leading singularities and total differentials in $ε d ln$ form. We show for the first time that it is possible to evaluate in…

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…
