Two-loop infrared singularities in the production of a Higgs boson associated with a top-quark pair
Journal of High Energy Physics, 2022 The associated production of a Higgs boson and a top-quark pair is important for probing the Yukawa coupling of the top quark, and calls for better theoretical modeling.

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.

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 ...

The CP-conserving two-Higgs-doublet model: the approach to the decoupling limit [PDF]
, 2002 A CP-even neutral Higgs boson with Standard-Model-like couplings may be the lightest scalar of a two-Higgs-doublet model. We study the decoupling limit of the most general CP-conserving two-Higgs-doublet model, where the mass of the lightest Higgs scalar

Discovery Prospects for NMSSM Higgs Bosons at the High-Energy Large Hadron Collider [PDF]
, 2014 We investigate the discovery prospects for NMSSM Higgs bosons during the 13~TeV run of the LHC. While one of the neutral Higgs bosons is demanded to have a mass around 125~GeV and Standard Model (SM)-like properties, there can be substantially lighter ...

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 ...

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 ...

Combined Analysis of CP Properties of Higgs Boson in Effective Higgs Lagrangian [PDF]
Communications in Theoretical Physics, 2016 Summary: CP violation effects of the Higgs stem from not only the CP mixing state but also the CP-violation couplings to electroweak bosons. The two CPV sources are combinedly studied based on an effective Higgs Lagrangian. The constraints from unitarity limits for \(WW\) and \(ZZ\) scatterings are investigated.

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.

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract The integration of artificial intelligence (AI), the rise of mega‐journals, and the manipulation of impact factors present challenges to scientific integrity. These trends threaten the core principles of objectivity, reproducibility, and transparency.
