Composite Higgs Search at the LHC [PDF]

, 2010
The Higgs boson production cross-sections and decay rates depend, within the Standard Model (SM), on a single unknown parameter, the Higgs mass.

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios

Advances in High Energy Physics, 2022
We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties.

Properties and searches of the exotic neutral Higgs bosons in the Georgi-Machacek model [PDF]

Journal of High Energy Physics, 2015
The Georgi-Machacek model predicts the existence of four neutral Higgs bosons, one of which can be identified as the 125-GeV Higgs boson. The latest Higgs data favor the parameter space of small mixing angle α between the two custodial singlets of the ...

Analytic approximations of 2 → 2 processes with massive internal particles

Journal of High Energy Physics, 2023
We consider two-loop corrections to 2 → 2 scattering processes with massive particles in the final state and massive particles in the loop. We discuss the combination of analytic expansions in the high-energy limit and for small Mandelstam variable t ...

Unparticles-Higgs Interplay [PDF]

, 2007
We show that scalar unparticles coupled to the Standard Model Higgs at the renormalizable level can have a dramatic impact in the breaking of the electroweak symmetry already at tree level.

The scale of new physics from the Higgs couplings to γγ and γZ

Journal of High Energy Physics, 2022
Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing processes that ...

Distinguishing a MSSM Higgs Boson from the SM Higgs Boson at a Linear Collider [PDF]

, 2001
The decoupling properties of the Higgs sector in the Minimal Supersymmetric Standard Model (MSSM) imply that a light CP-even Higgs boson discovered at the Tevatron or LHC may closely resemble the Standard Model (SM) Higgs boson.

Exploring Higgs-photon production at the LHC

Journal of High Energy Physics, 2023
We have investigated the signal for physics beyond the Standard Model via Higgs plus photon final state, hitherto unobserved at the LHC, in the framework of Standard Model Effective Field Theory.

Unbinned multivariate observables for global SMEFT analyses from machine learning

Journal of High Energy Physics, 2023
Theoretical interpretations of particle physics data, such as the determination of the Wilson coefficients of the Standard Model Effective Field Theory (SMEFT), often involve the inference of multiple parameters from a global dataset.

Higgs boson decay to charmonia via c-quark fragmentation

Journal of High Energy Physics, 2022
We calculate the decay branching fractions of the Higgs boson to J/ψ and η c via the charm-quark fragmentation mechanism for the color-singlet and color-octet states in the framework of non-relativistic QCD.
