Muon-electron scattering at NLO
Journal of High Energy Physics, 2019 We consider the process of muon-electron elastic scattering, which has been proposed as an ideal framework to measure the running of the electromagnetic coupling constant at space-like momenta and determine the leading-order hadronic contribution to the ...

The complete NLO corrections to dijet hadroproduction [PDF]
, 2016 We study the production of jets in hadronic collisions, by computing all contributions proportional to $\alpha_S^n\alpha^m$, with $n+m=2$ and $n+m=3$. These correspond to leading and next-to-leading order results, respectively, for single-inclusive and ...

Master integrals for the NNLO virtual corrections to μe scattering in QED: the planar graphs
Journal of High Energy Physics, 2017 We evaluate the master integrals for the two-loop, planar box-diagrams contributing to the elastic scattering of muons and electrons at next-to-next-to leading-order in QED.

Charge asymmetry in electron/positron energy loss in nuclear Bremsstrahlung
Journal of High Energy Physics, 2021 We calculate the leading Coulomb correction to the Bremsstrahlung energy loss in the electron-nucleus collisions for arbitrary energy of the incoming particle. This correction determines the charge asymmetry, i.e., the difference of electron and positron

Four-lepton production at hadron colliders: aMC@NLO predictions with theoretical uncertainties [PDF]
, 2011 We use aMC@NLO to study the production of four charged leptons at the LHC, performing parton showers with both HERWIG and Pythia6. Our underlying matrix element calculation features the full next-to-leading order $O(\alpha_S)$ result and the $O(\alpha_S ...

The one-loop amplitudes for Higgs + 4 partons with full mass effects
Journal of High Energy Physics, 2020 We present compact analytic formulae for the one-loop amplitudes for Higgs + 4 parton scattering, 0 → ggggh, 0 → q ¯ $$ \overline{q} $$ qggh and 0 → q ¯ $$ \overline{q} $$ q q ¯ ′ $$ {\overline{q}}^{\prime } $$ q′h, mediated by a loop of massive coloured

NLO QCD+EW predictions for HV and HV +jet production including parton-shower effects
Journal of High Energy Physics, 2017 We present the first NLO QCD+EW predictions for Higgs boson production in association with a ℓν ℓ or ℓ + ℓ − pair plus zero or one jets at the LHC. Fixed-order NLO QCD+EW calculations are combined with a QCD+QED parton shower using the recently developed

Gluon fragmentation into quarkonium at next-to-leading order using FKS subtraction
Journal of High Energy Physics, 2019 We present the calculation at next-to-leading order (NLO) in α s of the fragmentation function of a gluon into heavy quarkonium in the color-octet spin-singlet S-wave channel.

Diphoton production in vector-boson scattering at the LHC at next-to-leading order QCD
Journal of High Energy Physics, 2020 In this paper, we present results at next-to-leading order (NLO) QCD for photon pair production in association with two jets via vector boson scattering within the Standard Model (SM), and also in an effective field theory framework with anomalous gauge ...
