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 ...

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.

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.

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 ...

Higgs boson pair production in non-linear Effective Field Theory with full m t -dependence at NLO QCD

open access: yesJournal of High Energy Physics, 2018
We present a calculation of the NLO QCD corrections to Higgs boson pair production within the framework of a non-linearly realised Effective Field Theory in the Higgs sector, described by the electroweak chiral Lagrangian.

Gluon fusion contribution to HBB (B = H, γ, Z) at the LHC

open access: yesEPJ Web of Conferences, 2016
We have calculated one-loop amplitudes for the production of Higgs boson in association with two electroweak bosons (H, γ, Z) via gluon-gluon fusion. We present preliminary results for the total cross section at 8, 13 and 100 TeV center-of-mass energies ...

Higgs anomalous couplings, FCNC and LFV decays

open access: yes, 2019
An overview of searches for the lepton flavor violating decays of the Higgs boson, and for flavor changing neutral currents in Hqt couplings are presented from the ATLAS. In addition, different approaches on the Higgs anomalous couplings to vector bosons from the two experiments are presented.

Single Higgs production at LHC as a probe for an anomalous Higgs self coupling [PDF]

open access: yesProceedings of 38th International Conference on High Energy Physics — PoS(ICHEP2016), 2017
We explore the possibility of probing the trilinear Higgs self coupling indirectly, through single Higgs production and decay processes. The method relies on the effects that electroweak loops featuring an anomalous trilinear coupling would imprint on single Higgs production at the LHC.
