e+e− → ZH process in the SMEFT beyond leading order Open
A bstract We systematically study potential effects of Beyond the Standard Model physics in the e + e − → ZH process. To this end, we include all relevant dimension-6 Standard Model Effective Field Theory operators and work to next-to-lead…

QCD corrections to Higgs boson production and decay in weak boson fusion Open
We study QCD corrections to the process where a Higgs boson is produced in weak boson fusion and then decays into a pair of massive b quarks. We find that typical experimental criteria used to identify b jets in this process affect QCD cor…

Impact of NLO Weak SMEFT Corrections in $e^+e^- \rightarrow ZH$ Open
We present results from a complete next-to-leading order (NLO) calculation of $e^+e^-\rightarrow ZH$ in the Standard Model Effective Field Theory (SMEFT) framework, including all contributions from dimension-6 operators. At NLO, there are …

Nonfactorizable corrections to Higgs boson production in weak boson fusion Open
We discuss the nonfactorizable corrections to Higgs boson production in weak boson fusion at the Large Hadron Collider. Such corrections depend on the finite part of the two-loop virtual amplitude qQ→q′Q′+H which, up to now, has only been …

Non-factorisable contributions to t-channel single top and VBF Higgs production Open
We discuss non-factorisable contributions to two processes, $t$-channel single top production and Higgs production in vector boson fusion. Non-factorisable contributions are often neglected since they enter for the first time at next-to-ne…

Bremsstrahlung from neutrino scattering via magnetic dipole moments Open
In this paper, we discuss bremsstrahlung induced by neutrino scattering. This process should exist since neutrinos are expected to couple to photons via magnetic dipole and transition moments. These moments are loop-induced and tiny in the…

On the non-factorizable corrections to Higgs boson production in weak boson fusion Open
We discuss the non-factorizable corrections to Higgs boson production in weak boson fusion at the Large Hadron Collider. Such corrections depend on the finite part of the two-loop virtual amplitude $q \, Q \rightarrow q^\prime \, Q^\prime …
View article: Double insertions of SMEFT operators in gluon fusion Higgs boson production
Double insertions of SMEFT operators in gluon fusion Higgs boson production Open
Deviations from the Standard Model (SM) can be parametrized in terms of the SM effective field theory (SMEFT), which is typically truncated at dimension-6. Including higher dimension operators—as well as considering simultaneous insertions…

Anomalous Higgs boson couplings in weak boson fusion production at NNLO in QCD Open
The production of Higgs bosons in weak boson fusion has the second largest cross section among Higgs-production processes at the Large Hadron Collider. As such, this process plays an important role in detailed studies of Higgs interactions…

arXiv : NNLO QCD corrections to weak boson fusion Higgs boson production in the $H \to b\bar b$ and $H \to WW^* \to 4l$ decay channels Open
We compute the next-to-next-to-leading order QCD corrections to Higgs boson production in weak boson fusion followed by its decay to a $b\bar b$ pair or to a pair of leptonically-decaying $W$ bosons. Our calculation allows us to compute re…

Analytic results for deep-inelastic scattering at NNLO QCD with the nested soft-collinear subtraction scheme Open
We present analytic results that describe fully-differential NNLO QCD corrections to deep-inelastic scattering processes within the nested soft-collinear subtraction scheme. This is the last building block required for the application of t…
