Anomalous couplings in Higgs-boson pair production at approximate NNLO QCD
Journal of High Energy Physics, 2021 We combine NLO predictions with full top-quark mass dependence with approximate NNLO predictions for Higgs-boson pair production in gluon fusion, including the possibility to vary coupling parameters within a non-linear Effective Field Theory framework ...

Machine learning the trilinear and light-quark Yukawa couplings from Higgs pair kinematic shapes
Journal of High Energy Physics, 2022 Revealing the Higgs pair production process is the next big challenge in high energy physics. In this work, we explore the use of interpretable machine learning and cooperative game theory for extraction of the trilinear Higgs self-coupling in Higgs pair

SMEFTs living on the edge: determining the UV theories from positivity and extremality
Journal of High Energy Physics, 2022 We study the “inverse problem” in the context of the Standard Model Effective Field Theory (SMEFT): how and to what extend can one reconstruct the UV theory, given the measured values of the operator coefficients in the IR?

Portraying double Higgs at the Large Hadron Collider II
Journal of High Energy Physics, 2022 The Higgs potential is vital to understand the electroweak symmetry breaking mechanism, and probing the Higgs self-interaction is arguably one of the most important physics targets at current and upcoming collider experiments.

Anomalous couplings in single Higgs production through γγ collisions [PDF]
Zeitschrift f�r Physik C Particles and Fields, 1995 We show that single Higgs production in $ $ collisions through laser backscattering provides the best way to look for New Physics (NP) effects inducing anomalous Higgs couplings. Our analysis is based on the four $dim=6$ operators $ _{UB}$, $ _{UW}$, $\ol _{UB}$ and $\ol _{UW}$ which describe New Physics effects in this sector.

Positivity bounds at one-loop level: the Higgs sector
Journal of High Energy Physics, 2023 In this paper, we promote the convex cone method of positive bounds from tree level to loop level. This method is general and can be applied to obtain leading s 2 positivity bounds on the forward scattering process in the standard model effective field ...
