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, $a_{\mu}^{\textrm{HLbL};P}$.

Vacuum pseudoscalar susceptibility [PDF]
Physical Review C, 2010 We derive a novel model-independent result for the pion susceptibility in QCD via the isovector-pseudoscalar vacuum polarisation. In the neighbourhood of the chiral-limit, the pion susceptibility can be expressed as a sum of two independent terms. The first expresses the pion-pole contribution.

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 ...

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 ...

Light-cone distribution amplitudes of pseudoscalar mesons from lattice QCD [PDF]
Journal of High Energy Physics, 2019 We present the first lattice determination of the two lowest Gegenbauer moments of the leading-twist pion and kaon light-cone distribution amplitudes with full control of all errors: a2π=0.101−24+24\documentclass[12pt]{minimal} \usepackage{amsmath ...

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.
