Search for anomalous couplings in the Higgs sector at LEP [PDF]

Physics Letters B, 2000
Anomalous couplings of the Higgs boson are searched for through the processes e^+ e^- -> H gamma, e^+ e^- -> e^+ e^- H and e^+ e^- -> HZ. The mass range 70 GeV < m_H < 190 GeV is explored using 602 pb^-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies sqrt(s)=189-209 GeV.

Anomalous Higgs Yukawa couplings [PDF]

EPL (Europhysics Letters), 2014
In the standard model, the Higgs boson $h$ couples to the quarks and charged leptons according to the well-known formula $(m_ψ/v) h \barψψ$, where $ψ$ = quark (q) or lepton (l) and $v$ = 246 GeV is its vacuum expectation value. Suppose $m_ψ$ is of radiative origin instead, then the effective $h \barψψ$ Yukawa coupling will not be exactly $m_ψ/v$.

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

Probing non-standard HVV (V = W, Z) couplings in single Higgs production at future electron-proton collider

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).
