Pseudoscalar mesons and instantons [PDF]

open access: yesNuclear Physics B, 1983
Abstract We discuss the QCD sum rules for the correlators of pseudoscalar currents with quantum numbers of π, K, η, η′ mesons. In the framework of the instanton model of the QCD vacuum suggested earlier by the author, we calculate SU(3) breaking effects such as K, η masses and ηη′ mixing, as well as the U(1) breaking effect, the η′ mass.

Probing light pseudoscalar particles using synchrotron light [PDF]

open access: yes, 2009
The need for purely laboratory-based light pseudoscalar particles searches has been emphasized many times in the literature, since astrophysical bounds on these particles rely on several assumptions to calculate the flux produced in stellar plasmas.

Search for dark matter produced in association with a Higgs boson decaying to a τ lepton pair in proton-proton collisions at $$\sqrt{s}=13$$ TeV

open access: yesJournal of High Energy Physics
A search for dark matter particles produced in association with a Higgs boson decaying into a pair of τ leptons is performed using data collected in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector.

Remarks on Pseudoscalar Higgs Particles [PDF]

open access: yes, 1991
It is suggested that Z decays into three pseudoscalar Higgs particles can be a useful process in search for Higgs particles beyond the standard model.

Radiative decays of vector and pseudoscalar nonets

open access: yesEPJ 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 ...

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

open access: yesJournal 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.

The signatures of the pseudoscalar glueball

open access: yesNuclear Physics B, 1990
Abstract The predominance of the strange mesons decay modes for the pseudoscalar glueball and the Dalitz distributions are obtained, starting from a low-energy theorem based on chiral lagrangians, and extrapolating it to realistic energies by including K ∗ (892) and K 0 ∗ (1430) contributions.

Pseudoscalar-photon interactions, axions, non-minimal extensions, and their empirical constraints from observations [PDF]

open access: yes, 2010
Pseudoscalar-photon interactions were proposed in the study of the relations among equivalence principles. The interaction of pseudoscalar axion with gluons was proposed as a way to solve the strong CP problem.
