Title: Higgs alignment and novel $C P$ -violating observables in two-Higgs-doublet models

Abstract

Null results from searches for new physics at the Large Hadron Collider (LHC) tend to enforce the belief that new particles must be much heavier than the weak scale. We undertake a systematic study of the interplay between Higgs alignment and CP-violation in complex two-Higgs-doublet models, which enables us to construct a CP-violating scenario where new Higgs bosons are close to the weak scale after including stringent constraints from the electric dipole moment and measurements at the LHC. In addition, we propose a novel potential signal of CP-violation in the Higgs-to-Higgs decays, h₃ → h₂h₁, where h₃, h₂, and h₁ are the heaviest, second heaviest and the Standard Model-like neutral Higgs bosons, respectively. The decay could manifest itself in triple boson final states in h₁h₁h₁ and h₁h₁Z, which are quite distinct and provide unique venues for new measurements at the LHC.

$C P$ -violating Higgs boson ditau decays: Baryogenesis and Higgs factories

Journal Article Ge, Shao-Feng ; Li, Gang ; Pasquini, Pedro ; ... - Physical Review D

We demonstrate how probes of CP-violating observables in Higgs boson ditau decays at prospective future lepton colliders could provide a test of weak scale baryogenesis with significant discovery potential. Measurements at the Circular Electron Positron Collider, for example, could exclude a CP phase larger than 2.9° (5.6°) at 68% (95%) C.L. assuming the Standard Model value for magnitude of the tau lepton Yukawa coupling. Conversely, this sensitivity would allow for a 5σ discovery for 82% of the CP phase range [0, 2π). The reaches of the Future Circular Collider for electrons and positrons (FCC-ee) and International Linear Collider are comparable.more »« less

[ital CP] violation in the bosonic sector of the SM with two Higgs doublets

Journal Article Cvetic, G - Physical Review, D (Particles Fields); (United States)

We investigate [ital CP]-violation effects in the bosonic sector of the standard model (SM) with two Higgs doublets. First we calculate the mass eigenstates of the physical neutral Higgs bosons for the small but nonzero [ital CP]-violation parameter [xi][sub *], and then a forward-backward'' asymmetry [ital scrA][sub FB] for the decay [ital H][r arrow][ital W][sup +][ital W[minus]][ital Z] that would be a signal of [ital CP] violation. Although the effects are in general small ([ital scrA][sub FB]=[Gamma][sub FB]/[Gamma][similar to]10[sup [minus]3]), [ital scrA][sub FB] turns out to be a rather clean signal of [ital CP] violation, since neither the [ital CP]-conservingmore »« less

Enhanced di-Higgs production in the two Higgs doublet model

Journal Article Babu, K. S. ; Jana, Sudip - Journal of High Energy Physics (Online)

We show that the rate for di-Higgs production at the LHC can be enhanced by a factor as large as 25 compared to the Standard Model value in the two Higgs doublet model, while being consistent with the known properties of the observed Higgs boson h. There are correlated modifications inmore »« less
