Backreaction of electromagnetic fields and the Schwinger effect in pseudoscalar inflation magnetogenesis [PDF]
Physical Review D, 2019 We study magnetogenesis in axion-like inflation driven by a pseudoscalar field $\phi$ coupled axially to the electromagnetic (EM) field $(\beta/M_{p})\phi F_{\mu\nu}\tilde{F}^{\mu\nu}$ with dimensionless coupling constant $\beta$.

Pseudoscalar mass effects in the decays of τ with three pseudoscalar mesons [PDF]
Physical Review D, 1994 We study the effects of non-vanishing pseudoscalar masses in $ $ decays into three mesons. The hadronic matrix elements are obtained by using the generalized structure of the chiral currents with nonvanishing pseudoscalar masses and implementing the low-lying resonances in the different channels.

On the photon-pseudoscalar particle mixing in media and external fields
European Physical Journal C: Particles and Fields, 2021 In this work, I study the mixing of photons with pseudoscalar particles and vice-versa in the presence of an external magnetic field and a pseudoscalar field.

Pseudoscalar-pole contribution to the $(g_{\mu}-2)$: a rational approach [PDF]
, 2017 We employ a mathematical framework based on rational approximants in order to calculate the pseudoscalar-pole piece of the hadronic light-by-light contribution to the anomalous magnetic moment of the muon, $a_{\mu}^{\textrm{HLbL};P}$.

Simplified dark matter models with two Higgs doublets: I. Pseudoscalar mediators [PDF]
Journal of High Energy Physics, 2017 We study a new class of renormalisable simplified models for dark matter searches at the LHC that are based on two Higgs doublet models with an additional pseudoscalar mediator.

Determination of the strong vertices of doubly heavy baryons with pseudoscalar mesons in QCD [PDF]
, 2020 The strong coupling constant of doubly heavy baryons with light pseudoscalar mesons $ \pi $ and $ K $ are computed within the light cone sum rules. We take into account two-particle and three-particle distribution amplitudes of the said pseudoscalar ...

Production of a Higgs pseudoscalar plus two jets in hadronic collisions [PDF]
, 1998 We consider the production of a Higgs pseudoscalar accompanied by two jets in hadronic collisions. We work in the limit that the top quark is much heavier than the Higgs pseudoscalar and use an effective Lagrangian for the interactions of gluons with the

Pseudoscalar Mesons and Emergent Mass [PDF]
Few-body systemsDespite its role in the continuing evolution of the Universe, only a small fraction of the mass of visible material can be attributed to the Higgs boson alone.

Loop corrections to dark matter direct detection in a pseudoscalar mediator dark matter model [PDF]
Journal of High Energy Physics, 2018 A bstractIf dark matter (DM) is a fermion and its interactions with the standard model particles are mediated by pseudoscalar particles, the tree-level amplitude for the DM-nucleon elastic scattering is suppressed by the momentum transfer in the non ...

Vectorlike leptons and long-lived bosons at the LHC
Journal of High Energy Physics, 2023 We study a renormalizable theory that includes a heavy weak-singlet vectorlike lepton, τ ′ , that decays into a pseudoscalar boson and a tau lepton. We show that this can be the dominant decay mode of τ ′ provided the pseudoscalar couplings deviate from ...
