, 1999 Abstract The scalar sector of the standard model (SM) consists of only one doublet with weak hypercharge Y = 1/2. Most extensions of the SM include an enlargement of the Higgs sector. There are many theoretical motivations to enlarge the scalar sector of the standard electroweak theory, even if one only considers extensions of that ...

New tools for dissecting the general 2HDM
Journal of High Energy Physics, 2023 Two Higgs doublet models (2HDM) provide the low energy effective theory (EFT) description in many well motivated extensions of the Standard Model. It is therefore relevant to study their properties, as well as the theoretical constraints on these models.

Collider phenomenology of new neutral scalars in a flavored multi-Higgs model
Physical Review D, 2023 In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signature, particular relevant in the context of the Large Hadron Collider (LHC) measurements, is based on a topology with two charged leptons and four jets arising from first and

CP-violation, asymmetries and interferences in t t ¯ ϕ $$ t\overline{t}\phi $$
Journal of High Energy Physics, 2022 In this paper, we use the associated production of top-quark pairs ( t t ¯ $$ t\overline{t} $$ ) with a generic scalar boson (ϕ) at the LHC (pp → t t ¯ ϕ $$ t\overline{t}\phi $$ ) to explore the sensitivity of a large set of observables to the sign of ...

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.

Geometrical CP violation in multi-Higgs models [PDF]
Journal of High Energy Physics, 2012 We introduce several methods to obtain calculable phases with geometrical values that are independent of arbitrary parameters in the scalar potential. These phases depend on the number of scalars and on the order of the discrete non-Abelian group considered.

Minima of multi-Higgs potentials with triplets of Î(3n2) and Î(6n2)
Physics Letters B, 2017 We analyse the minima of scalar potentials for multi-Higgs models where the scalars are arranged as either one triplet or two triplets of the discrete symmetries A4, S4, Î(27), Î(54), as well as Î(3n2) and Î(6n2) with n>3.

CP violation in a model with Higgs triplets
Journal of High Energy Physics, 2023 We discuss CP-violation in a model with a real and a complex isospin triplet Higgs fields without introducing any symmetries except for the electroweak gauge symmetry.

Advanced Materials, EarlyView.ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...
