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.

On the study of the Higgs properties at a muon collider [PDF]
Modern Physics Letters A, 2015 The discovery of the Higgs particle at 125 GeV is demanding a detailed knowledge of the properties of this fundamental component of the Standard Model. To that aim various proposals of electron and muon colliders have been put forward for precision studies of the partial widths of the various decay channels.

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.

Higgs properties and fourth generation leptons
Physical Review D, 2011 It is possible that there are additional vector-like generations where the quarks have mass terms that do not originate from weak symmetry breaking, but the leptons only get mass through weak symmetry breaking. We discuss the impact that the new leptons have on Higgs boson decay branching ratios and on the range of allowed Higgs masses in such a model (

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 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 ...

Beyond the Standard Model Higgs sectors
, 2020 Although the experimentally detected 125 GeV spin-0 resonance has properties very close to the one predicted by the Standard Model, it is still possible that the Higgs sector in nature is not SM-like.

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.

Deep learning to improve the sensitivity of Di-Higgs searches in the 4b channel
Journal of High Energy PhysicsThe study of di-Higgs events, both resonant and non-resonant, plays a crucial role in understanding the fundamental interactions of the Higgs boson.

Advanced Materials, EarlyView.We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.
