Two-loop mixed QCD-electroweak amplitudes for Z+jet production at the LHC: bosonic corrections
Journal of High Energy PhysicsWe present a calculation of the bosonic contribution to the two-loop mixed QCD-electroweak scattering amplitudes for Z-boson production in association with one hard jet at hadron colliders.

Quark and Gluon Form Factors at Three Loops in Perturbative QCD [PDF]
, 2009 We compute the quark and gluon form factors at up to three-loop order within massless perturbative Quantum Chromodynamics by studying the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons.

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Precision phenomenology at multi-TeV muon colliders
Journal of High Energy PhysicsFuture lepton colliders, such as those based on linear e + e − or circular μ + μ − accelerators, are expected to attain centre-of-mass energies in the multi-TeV range.

Electroweak oblique parameters as a probe of the trilinear Higgs boson self-interaction [PDF]
, 2017 We calculate the two-loop contributions from a modified trilinear Higgs self-interaction, κλλSMvh3, to the electroweak oblique parameters S and T. Using the current bounds on S and T from electroweak measurements, we find the 95% C.L.

Simulation of a Three‐Nucleons System Transition on Quantum Circuits
Advanced Quantum Technologies, Volume 8, Issue 5, May 2025.A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

NLO EW and QCD corrections to polarised same-sign WW scattering at the LHC
Journal of High Energy PhysicsWe present the first calculation of same-sign WW scattering at the LHC in the fully leptonic decay channel including the modelling of polarisation for intermediate electroweak bosons and radiative corrections up to NLO EW+QCD accuracy.

Complete SMEFT predictions for four top quark production at hadron colliders
Journal of High Energy Physics, 2022 We study four top quark production at hadron colliders in the Standard Model Effective Field Theory (SMEFT). We perform an analysis at the tree-level, including all possible QCD- and EW-coupling orders and relevant dimension-six operators.

Precise prediction for the light MSSM Higgs-boson mass combining effective field theory and fixed-order calculations [PDF]
, 2016 In the Minimal Supersymmetric Standard Model heavy superparticles introduce large logarithms in the calculation of the lightest -even Higgs-boson mass. These logarithmic contributions can be resummed using effective field theory techniques.

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron
