1. NNLO QCD Predictions for Wγγ Production at the LHC

Paolo Garbarino (University of Zurich (UZH))

10/04/2026, 12:00

Triboson production processes play a crucial role in probing the electroweak sector of the Standard Model (SM), as they involve quartic gauge-boson couplings already at the tree level. Moreover, they provide an irreducible background to other important SM processes. Despite the corresponding cross sections being much smaller than for diboson processes—extensively studied for triple gauge...

4. Towards two-loop EW corrections in OpenLoops

Lorenzo Mai (University of Genova & INFN)

10/04/2026, 12:15

At energies above the Electroweak (EW) scale, higher-order EW corrections exhibit a logarithmic enhancement which is driven by the ratio of the typical scattering energy to the gauge-boson mass. At next-to-leading order (NLO) these corrections lead to factors amounting to several tens of percent in tails of kinematic distributions of crucial LHC processes, and still contribute a few percent at...

23. Towards two-loop EW corrections to the Drell-Yan process

Tommaso Armadillo (Istituto Nazionale di Fisica Nucleare)

10/04/2026, 12:30

In the context of the precision physics programme at the HL-LHC and the FCC-ee, electroweak corrections will play a central role. In this talk, I will discuss recent developments in the computation of two-loop electroweak amplitudes to lepton-pair production. First, I will present the ultraviolet-renormalised and infrared-subtracted finite remainder of the two-loop amplitude in quantum...
