Constraining the anomalous Higgs boson coupling in ${\bf H+\gamma} $ production
Chinese Physics C, 2019 Higgs boson production in association with a photon ($H$+$\gamma$) offers a promising channel to test the Higgs boson to photon coupling at various energy scales. Its potential sensitivity to anomalous couplings of the Higgs boson has not been explored with the proton-proton collision data.

Anomalous Higgs Yukawa Couplings and Recent LHC Data
Meeting 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 infamous 95 GeV b b ¯ $$ \textrm{b}\overline{\textrm{b}} $$ excess at LEP: two b or not two b?
Journal of High Energy PhysicsA 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.

W boson polarization as a measure of gauge-Higgs anomalous couplings at the LHC
Nuclear Physics B, 2019 We show how the $W$ boson polarization in the process of associated $W^{\pm}H$ production at the Large Hadron Collider (LHC) can be used to constrain anomalous $WWH$ couplings. We first calculate the spin density matrix for the $W$ to linear order in the anomalous couplings, which are assumed to be small.

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

Precision Higgs width and couplings with a high energy muon collider
Journal of High Energy PhysicsThe 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.

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