Two-loop light-quark Electroweak corrections to Higgs boson pair production in gluon fusion
Journal of High Energy PhysicsWe compute two-loop electroweak corrections to double Higgs boson production in gluon fusion mediated by light quarks in a fully analytical way. We determine a basis of master integrals satisfying canonical differential equations in dlog form, enhanced ...

Electron-positron annihilation into heavy leptons at two loops
Journal of High Energy PhysicsWe calculate the NNLO QED corrections to the C-even part of differential cross section of e + e − → μ + μ − process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov’s polylogarithms.

Mixed QCD-EW corrections to W-pair production at electron-positron colliders
Journal of High Energy PhysicsThe discrepancy between the CDF measurement and the Standard Model theoretical prediction for the W-boson mass underscores the importance of conducting high-precision studies on the W boson, which is one of the predominant objectives of proposed future e

The global electroweak Standard Model fit after the Higgs discovery
, 2013 We present an update of the global Standard Model (SM) fit to electroweak precision data under the assumption that the new particle discovered at the LHC is the SM Higgs boson.

EVAluation of the Equivalent Vector boson Approximation at highest energy colliders
Journal of High Energy PhysicsCollider processes at the highest available partonic center-of-mass energies — 10 TeV and above — exhibit a new regime of electroweak interactions where electroweak gauge bosons mostly act as quasi-massless partons in vector boson fusion processes.

Quantum properties of H → VV *: precise predictions in the SM and sensitivity to new physics
Journal of High Energy PhysicsWe study the quantum properties of the Higgs-boson decays into four fermions via two vector bosons (H → VV * → 4f). In particular, we focus on the case of two different-flavour lepton pairs (H → ZZ * → μ + μ − e + e − ).
