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.

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?

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

Journal of High Energy Physics, 2022 The couplings of the Higgs boson (H) with massive gauge bosons of weak interaction (V = W, Z), can be probed in single Higgs boson production at the proposed future Large Hadron-Electron Collider (LHeC).

Light-quark Yukawa couplings from off-shell Higgs production
Journal of High Energy Physics, 2023 Yukawa couplings of the first quark generation are notoriously difficult to constrain due to their small values within the Standard Model. Here we propose Higgs off-shell production, with the Higgs boson decaying to four leptons, as a probe of the up ...

ANOMALOUS HIGGS COUPLINGS [PDF]
International Journal of Modern Physics A, 1999 We review the effects of new effective interactions on Higgs-boson phenomenology. New physics in the electroweak bosonic sector is expected to induce additional interactions between the Higgs doublet field and the electroweak gauge bosons, leading to anomalous Higgs couplings as well as anomalous gauge-boson self-interactions.

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 $γγ$ 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 $Ø_{UB}$, $Ø_{UW}$, $\olØ_{UB}$ and $\olØ_{UW}$ which describe New Physics effects in this sector.

Effects of the anomalous Higgs couplings on the Higgs boson production at the Large Hadron Collider [PDF]
The European Physical Journal C, 2009 We study the impact of dimension-six operators on single- and double-Higgs production rates via gluon fusion at the Large Hadron Collider (LHC). If the top-Yukawa coupling is modified by some new physics whose scale is of the TeV scale, its effect changes the cross sections of single-Higgs production $gg\to H$ and double-Higgs production $gg\to HH ...
