Meson exchange model for pseudoscalar meson-meson scattering [PDF]

open access: yes, 1990
A dynamical model for pseudoscalar-pseudoscalar meson scattering based on meson exchange, suitable for use in a variety of low- and intermediate-energy mesonic interactions, has been constructed and applied to ππ and kπ scattering with good quantitative ...

Pseudoscalar meson dominance and nucleon structure [PDF]

open access: yes, 2023
Pseudoscalar meson dominance has implications for nucleon structure which follow from an Extended Partial Conservation of the Axial Current (EPCAC). The minimal resonance saturation of the nucleon pseudoscalar form factor of the lowest pseudoscalar and ...

Search for a low-mass pseudoscalar Higgs boson produced in association with a bb‾ pair in pp collisions at s=8 TeV

open access: yesPhysics Letters B, 2016
A search is reported for a light pseudoscalar Higgs boson decaying to a pair of τ leptons, produced in association with a bb‾ pair, in the context of two-Higgs-doublet models. The results are based on pp collision data at a centre-of-mass energy of 8 TeV

Two and three pseudoscalar production in e + e − annihilation and their contributions to (g − 2) μ

open access: yesJournal of High Energy Physics, 2021
A coherent study of e + e − annihilation into two (π + π − , K + K − ) and three (π + π − π 0 , π + π − η) pseudoscalar meson production is carried out within the framework of resonance chiral theory in energy region E ≲ 2 GeV. The work of [L.Y.

The Isgur-Wise function: A lattice determination from pseudoscalar → pseudoscalar form factors [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1994
Form factors for pseudoscalar --> pseudoscalar decays of heavy-light mesons are found in quenched lattice QCD with heavy-quark masses in the range of approximately 1-2 GeV. The Isgur-Wise function, $ξ(ω)$, is extracted from these form factors. Results are in good agreement with $ξ(ω)$ derived from CLEO measurements for B --> D*.

Magneto-optic effects of the cosmic microwave background

open access: yesNuclear Physics B, 2018
Generation of magneto-optic effects by the interaction of the CMB with cosmic magnetic fields is studied. Effects which generate polarization such as the Cotton–Mouton effect, vacuum polarization and photon–pseudoscalar mixing in external magnetic field ...

The a0(980) in the single Cabibbo-suppressed process Λc → π0ηp

open access: yesPhysics Letters B, 2023
In this work, we have investigated the Cabibbo-suppressed process Λc→π0ηp, by taking into account the intermediate scalar state a0(980), which could be dynamically generated from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary ...

Vacuum pseudoscalar susceptibility [PDF]

open access: yesPhysical 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.
