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 ...

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.

e + e − → ZH process in the SMEFT beyond leading order

open access: yesJournal of High Energy Physics
We systematically study potential effects of Beyond the Standard Model physics in the e + e − → ZH process. To this end, we include all relevant dimension-6 Standard Model Effective Field Theory operators and work to next-to-leading order (NLO) accuracy ...

A log story short: running contributions to radiative Higgs decays in the SMEFT

open access: yesJournal of High Energy Physics
We investigate the renormalization of the radiative decays of the Higgs to two gauge bosons in the Standard Model Effective Field Theory at mass dimension eight.

Exotic h → Za Higgs decays into τ leptons

open access: yesJournal of High Energy Physics
Exotic Higgs decays are among the most promising areas to be explored at the High-Luminosity LHC, given the unprecedentedly large amount (~ 3 × 108) of 125 GeV Higgs bosons that will be produced. In this context, we propose a new search channel for which

Lepton flavor violation in Higgs boson decays at the HL-LHC

open access: yesJournal of High Energy Physics
We explore the discovery potential for lepton flavor-violating Higgs boson decays, h → ℓ i ℓ j (ℓ i ≠ ℓ j ; ℓ = e, μ, τ), in proton-proton collisions.

Energy growth in V L V L → V L V L , V L V L h scattering to probe Higgs cubic and HEFT interactions

open access: yesJournal of High Energy Physics
We compute the energy scales of perturbative unitarity violation in V L V L → V L V L h processes and compare them to V L V L → hhh process, where V L refers to a longitudinal mode of Z or W boson, and h the Higgs boson.
