Anomalous Higgs Couplings [PDF]

International Journal of Modern Physics A, 1999
We review the effects of new effective interactions on the 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 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 $(m_\psi/v) h \bar{\psi}\psi$, where $\psi$ = quark (q) or lepton (l) and $v$ = 246 GeV is its vacuum expectation value.

Anomalous Higgs Couplings at the LHeC [PDF]

Nuclear Physics B, 2013
The discovery of Higgs boson plays a crucial role in understanding the electroweak symmetry breaking sector. From now on, solving the dynamics of this sector needs precision measurements of the couplings of the Higgs boson to the standard model particles.

$ttH$ Anomalous Coupling in Double Higgs Production [PDF]

Journal of High Energy Physics, 2014
We study the effects of top-Higgs anomalous coupling in the production of a pair of Higgs boson via gluon fusion at the Large Hadron Collider (LHC). The introduction of anomalous $ttH$ coupling can alter the hadronic double Higgs boson cross section and ...

Anomalous Higgs Couplings as a Window to New Physics [PDF]

Physical Review D, 2013
The initial data on the production and decay of the Higgs boson reported significant deviations from the Standard Model (SM) expectations, prompting much speculation about its couplings to the other particles.

Anomalous gauge-boson couplings and the Higgs-boson mass [PDF]

The European Physical Journal C, 2004
We study anomalous gauge-boson couplings induced by a locally SU(2) x U(1) invariant effective Lagrangian containing ten operators of dimension six built from the boson fields of the Standard Model (SM) before spontaneous symmetry breaking (SSB).

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. The Higgs decay channels

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
