Anomalous Higgs Couplings as a Window to New Physics

Throughout this thesis, we investigate how effective field theories, combined with unitarization techniques, can be used to explore physics beyond the Standard Model, with particular emphasis on the dynamical origin of electroweak symmetry breaking. Since effective theories often produce amplitudes that violate unitarity at high energies, restoring ...

Probing new physics with the electron Yukawa coupling

Journal of High Energy Physics
A dedicated run of a future electron-positron collider (FCC-ee) at a center-of-mass energy equal to the Higgs boson mass would enable a direct measurement of the electron Yukawa coupling.

How large can the light quark Yukawa couplings be?

Journal of High Energy Physics
We investigate models that can induce significant modifications to the couplings of first- and second-generation quarks with Higgs bosons. Specifically, we identify all simplified models featuring two vector-like quark states which can lead to ...

Double Higgs production in vector boson fusion at NLO QCD in HEFT

Journal of High Energy Physics
We present the next-to-leading order QCD corrections to Higgs boson pair production in vector boson fusion, including the leading operators in the framework of Higgs Effective Field Theory (HEFT).

Higgs pair production in gluon fusion to higher orders in Higgs Effective Field Theory

Journal of High Energy Physics
Higgs pair production offers the opportunity to probe correlations among the couplings of one or two Higgs bosons to fermions and gauge bosons. In this context, it serves as a powerful test of the underlying Effective Field Theory (EFT) framework.
