Equivalence Theorems for Pseudoscalar Coupling [PDF]
, 1952 By a unitary transformation a rigorous equivalence theorem is established for the pseudoscalar coupling of pseudoscalar mesons (neutral and charged) to a second-quantized nucleon field. By the transformation the linear pseudoscalar coupling is eliminated

Pseudoscalar-pole contributions to the muon $g-2$ at the physical point [PDF]
, 2022 Pseudoscalar-pole diagrams are an important component of estimates of the hadronic light-by-light (HLbL) contribution to the muon g−2. We report on our computation of the transition form factors P→γ∗γ∗ for the neutral pseudoscalar mesons P=π0 and η .

NLO QCD corrections to pseudoscalar Higgs production in the MSSM [PDF]
, 2011 We present a calculation of the two-loop quark-squark-gluino contributions to pseudoscalar Higgs boson production via gluon fusion in the MSSM. We regularize the loop integrals using the Pauli-Villars method, and obtain explicit and compact analytic ...

SCALAR AND PSEUDOSCALAR GLUEBALLS [PDF]
International Journal of Modern Physics A, 2009 We employ two simple and robust results to constrain the mixing matrix of the isosinglet scalar mesons f0(1710), f0(1500), f0(1370): one is the approximate SU (3) symmetry empirically observed in the scalar sector above 1 GeV and confirmed by lattice QCD, and the other is the scalar glueball mass at 1710 MeV in the quenched approximation. In the SU (3)

Pseudoscalar mesons in a finite cubic volume with twisted boundary conditions [PDF]
, 2016 We study the effects of a finite cubic volume with twisted boundary conditions on pseudoscalar mesons. We first apply chiral perturbation theory in the p-regime and calculate the corrections for masses, decay constants, pseudoscalar coupling constants ...

A case for resonant X-ray Bragg diffraction by a collinear antiferromagnet Li<sub>2</sub>Ni<sub>3</sub>P<sub>4</sub>O<sub>14</sub>. [PDF]
Acta Crystallogr B Struct Sci Cryst Eng MaterAmplitudes for resonant X‐ray diffraction by collinear antiferromagnet Li2Ni3P4O14 that include permitted Dirac multipoles, e.g. anapoles, are investigated. Chiral signatures for the rotation of X‐ray helicity are described.Magnetic axial and polar (Dirac) nickel multipoles contribute to resonant X‐ray Bragg amplitudes in a symmetry‐informed analysis ...

Reconstructing a light pseudoscalar in the Type-X two Higgs doublet model
Physics Letters B, 2017 We investigate the detectability as well as reconstructibility of a light pseudoscalar particle A, of mass in the 50–60 GeV range, which is still allowed in a Type-X (lepton-specific) two-Higgs doublet scenario.

Doped holographic fermionic system
European Physical Journal C: Particles and Fields, 2020 We construct a two-current model. It includes two gauge fields, which introduce the doping effect, and a neutral scalar field. And then we numerically construct an AdS black brane geometry with scalar hair.
