ANOMALOUS HIGGS COUPLINGS [PDF]

open access: yesInternational 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]

open access: yesZeitschrift 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.

Combined search for the Higgs boson with the D0 experiment [PDF]

open access: yes, 2013
We perform a combination of searches for standard model Higgs boson production in $p\bar{p}$ collisions recorded by the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of $\sqrt{s}=1.96$ TeV.

Light-quark Yukawa couplings from off-shell Higgs production

open access: yesJournal 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 ...

Effects of the anomalous Higgs couplings on the Higgs boson production at the Large Hadron Collider [PDF]

open access: yesThe 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 ...

Search for charged Higgs bosons through the violation of lepton universality in tt¯ events using pp collision data at s√=7 TeV with the ATLAS experiment [PDF]

open access: yes, 2013
In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson H +, t → bH +, in addition to the Standard Model decay t → bW. Since W bosons decay to the three lepton generations equally, while H +

Anomalous couplings in associated VH production with Higgs boson decay to massive b quarks at NNLO in QCD [PDF]

open access: yes, 2021
We combine the NNLO QCD description of Higgs boson production in association with an electroweak vector boson V=W or Z with a similarly precise description of Higgs boson decays into a pair of massive b quarks and with the anomalous couplings that modify

Unitarity bounds on extensions of Higgs sector

open access: yesJournal of High Energy Physics, 2023
It is widely believed that extensions of the minimal Higgs sector is one of the promising directions for resolving many puzzles beyond the Standard Model (SM).

High precision higgs from high energy muon colliders

open access: yesJournal of High Energy Physics, 2022
Muon colliders are an exciting possibility for reaching the highest energies possible on the shortest timescale. They potentially combine the greatest strengths of e + e − and pp colliders by bridging the energy versus precision dichotomy.
