Novel probes for electron-muon flavor violation from exotic Higgs decays

Journal of High Energy Physics
In this paper, we propose two novel signatures of Higgs decays to search for electron-muon flavor violation. These signatures arise from the presence of a light pseudoscalar into which the 125-GeV Higgs boson decays.

Radiative decays of vector and pseudoscalar nonets

EPJ Web of Conferences, 2012
Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Pseudoscalar Higgs plus jet production at Next-to-Next-to-Leading Order in QCD

Journal of High Energy Physics
We present a calculation of pseudoscalar Higgs production in association with a jet at Next-to-Next-to Leading Order (NNLO) accuracy in QCD. We work in an effective field theory in which m t → ∞ resulting in effective operators which couple the ...

On the precision of a data-driven estimate of the pseudoscalar-pole contribution to hadronic light-by-light scattering in the muon g−2

EPJ Web of Conferences, 2016
The evaluation of the numerically dominant pseudoscalar-pole contribution to hadronic light-bylight scattering in the muon g − 2 involves the pseudoscalar-photon transition form factor FPγ*γ*(−Q12−Q22) with P = π0, η, η′ and, in general, two off-shell ...

Masses of purely top-quark bound states: toponium and the triply-top baryon

European Physical Journal C: Particles and Fields
We investigate the pseudoscalar ( $$\eta _t$$ η t ) and vector ( $$\psi _t$$ ψ t ) toponium states, as well as the triply-top baryon ( $$\Omega _{ttt}$$ Ω ttt ), using the QCD sum-rule method.

Thin layer axion dynamo

European Physical Journal C: Particles and Fields
We study interacting classical magnetic and pseudoscalar fields in frames of the axion electrodynamics. A large scale pseudoscalar field can be the coherent superposition of axions or axion like particles. We consider the evolution of these fields inside

Leptophilic ALPs in laboratory experiments

Journal of High Energy Physics
We study the collider phenomenology of leptophilic axion-like particles (ALPs), i.e. pseudoscalar particles that couple only to charged leptons. Loops of charged leptons induce effective interactions of the ALPs with photons, which depend on the momenta ...
