Pseudoscalar mass effects in the decays of τ with three pseudoscalar mesons [PDF]
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.

PSEUDOSCALAR MESON ELECTROPRODUCTION AND TRANSVERSITY [PDF]
Exclusive meson leptoproduction from nucleons in the deeply virtual exchanged boson limit can be described by generalized parton distributions (GPDs). Including spin dependence in the description requires 8 independent quark-parton and gluon-parton functions.

Pseudoscalar-photon Interactions, Axions, Non-Minimal Extensions, and Their Empirical Constraints from Observations [PDF]
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.

Nonminimally coupled pseudoscalar inflaton [PDF]
We consider a scenario in which the inflaton $ $ is a pseudoscalar field non-minimally coupled to gravity through a term of the form ${\cal X} R ^2$. The pseudoscalar is also coupled to a $U(1)$ gauge field (or an ensemble of ${\cal N}$ gauge fields) through an axial coupling of the form $ F \tilde{F}$. After M. M. Anber and L. Sorbo, Phys. Rev.

Pseudoscalar Form Factors in Tau-Neutrino Nucleon Scattering [PDF]
We investigate the pseudoscalar transition form factors of nucleon for quasi-elastic scattering and \Delta resonance production in tau-neutrino nucleon scattering via the charged current interactions.

We establish a new covariant phenomenological model, which describes an influence of pseudoscalar (axion) field on spins of test massive particles. The model includes general relativistic equations of particle motion and spin evolution in background ...

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