Anomalous Higgs Yukawa Couplings and Recent LHC Data

open access: yesMeeting Abstracts of the Physical Society of Japan, 2017
Very recently, the CMS collaboration has reported a search for the production for a Standard Model (SM) Higgs boson in association with a top quark pair ($t bar{t} H$) at the LHC Run-2 and a best fit $t bar{t} H$ yield of $1.5 pm 0.5$ times the SM prediction with an observed significance of $3.3 sigma$.

The anomalous 3-boson couplings as an implication of the Higgs sector

open access: yesZeitschrift f�r Physik C: Particles and Fields, 1993
We discuss the possible new electroweak interactions which may be generated by the Higgs sector at the scale of theZ mass. For this purpose, we give a set ofSU(2)×U(1) gauge invariant operators constructed in terms ofW, Z, γ and Higgs fields which in the unitary gauge describe all possible γWW andZWW anomalous couplings.

Precision Higgs width and couplings with a high energy muon collider

open access: yesJournal of High Energy Physics
The interpretation of Higgs data is typically based on different assumptions about whether there can be additional decay modes of the Higgs or if any couplings can be bounded by theoretical arguments.

Polarized $Z$ cross sections in Higgsstrahlung for the determination of anomalous $ZZH$ couplings [PDF]

open access: yes, 2022
The production of a Higgs boson in association with a $Z$ at an electron-positron collider is one of the cleanest methods for the measurement of the couplings of the Higgs boson.

Measurements of Higgs Boson Properties using the ATLAS Detector

open access: yesEPJ Web of Conferences, 2014
Measurements are presented of the production properties, couplings and spin-parity of the recently discovered Higgs-like boson using the decays into boson pairs, γγ, ZZ∗→ 4ℓ and WW∗→ ℓνℓν.

Testing the 2HDM explanation of the muon g – 2 anomaly at the LHC

open access: yesJournal of High Energy Physics, 2019
The discrepancy between the measured value and the Standard Model pre- diction for the muon anomalous magnetic moment is one of the important issues in the particle physics.

The infamous 95 GeV b b ¯ $$ \textrm{b}\overline{\textrm{b}} $$ excess at LEP: two b or not two b?

open access: yesJournal of High Energy Physics
A small deviation observed around 95 GeV in the diphoton invariant mass distribution in the LHC Run 2 data has been subject to considerable attention in the past couple of years.

Exploring anomalous HZγ couplings in γ-proton collisions at the LHC

open access: yesPhysics Letters B, 2016
The HZγ coupling, which is highly sensitive to the new physics beyond the standard model, is studied through the process pp→pγp→pHX at the LHC. To this purpose, an effective Lagrangian, in a model independent approach, with dimension six operators is ...

Studies of new Higgs boson interactions through nonresonant HH production in the b b ¯ γγ $$ b\overline{b}\gamma \gamma $$ final state in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for nonresonant Higgs boson pair production in the b b ¯ γγ $$ b\overline{b}\gamma \gamma $$ final state is performed using 140 fb −1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN ...

Expectations for probing the Higgs–fermion and the Higgs–vector boson couplings at the ILC

open access: yesPhysics Letters B, 2014
Deviations from the standard Higgs sector generated by some new physics at an energy scale Λ could be described by an effective SU(3)c×SU(2)L×U(1) invariant non-renormalizable Lagrangian terms of dimension six.
