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.

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.

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 ...

Probing the CP structure of the top quark Yukawa at the future muon collider

open access: yesJournal of High Energy Physics
We study the top-Higgs coupling with a CP violating phase ξ at a future multi-TeV muon collider. We focus on processes that are directly sensitive to the top quark Yukawa coupling: t t ¯ h $$ t\overline{t}h $$ , tbhμν, and t t ¯ hν ν ¯ $$ t\overline{t} h\

On the impact of the mixed Z/γ PDF at muon colliders

open access: yesJournal of High Energy Physics
We study the role of the Z/γ-interference parton distribution function (PDF) in high-energy muon colliders. We review how this PDF emerges when electroweak interactions are applied to the collinear splitting process and show that the leading-order ...
