Multi-Higgs boson production with anomalous interactions at current and future proton colliders

Journal of High Energy Physics
We investigate multi-Higgs boson production at proton colliders, in a framework involving anomalous interactions, focusing on triple Higgs boson production.

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 ...

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

Journal 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.

Measurements of Higgs Boson Properties using the ATLAS Detector

EPJ 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.

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.

Probing the spin-parity of the Higgs boson via jet kinematics in vector boson fusion

, 2013
Determining the spin and the parity quantum numbers of the recently discovered Higgs-like boson at the LHC is a matter of great importance. In this paper, we consider the possibility of using the kinematics of the tagging jets in Higgs production via the

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

Journal 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.

Effective-Lagrangian approach to gamma gamma --> WW; II: Results and comparison with e+e- --> WW

, 2005
We present a study of anomalous electroweak gauge-boson couplings which can be measured in e+e- and gamma gamma collisions at a future linear collider like ILC.

Precision Higgs width and couplings with a high energy muon collider

Journal 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.

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

EPJ 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 ...
