The Schwinger Nonet Mass and Sakurai Mass-Mixing Angle Formulae Reexamined [PDF]

open access: yes, 1998
We study the origins of the inaccuracies of Schwinger's nonet mass, and the Sakurai mass-mixing angle, formulae for the pseudoscalar meson nonet, and suggest new versions of them, modified by the inclusion of the pseudoscalar decay constants.

Study of the pseudoscalar glueball in J/ψ radiative decays [PDF]

open access: yesPhysical Review D, 2019
We aim to explore the production rate of the pseudoscalar glueball in $J/\psi$ radiative decay by lattice QCD in quenched approximation. The calculation is performed on three anisotropic lattices with the spatial lattice spacing ranging from 0.222(2) fm ...

Spin-axion coupling [PDF]

open access: yes, 2015
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 ...

Nπ -state contamination in lattice calculations of the nucleon pseudoscalar form factor [PDF]

open access: yesPhysical Review D, 2019
The nucleon-pion-state contribution in the QCD 3-point function of the pseudoscalar density is calculated to leading order in chiral perturbation theory. It predicts a nucleon-pion-state contamination in lattice estimates for the pseudoscalar form factor

Chiral Properties of Pseudoscalar Mesons on a Quenched $20^4$ Lattice with Overlap Fermions [PDF]

open access: yes, 2001
The chiral properties of the pseudoscalar mesons are studied numerically on a quenched $20^4$ lattice with the overlap fermion. We elucidate the role of the zero modes in the meson propagators, particularly that of the pseudoscalar meson.

Decay constants of pseudoscalar and vector mesons with improved holographic wavefunction [PDF]

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2018
We calculate the decay constants of light and heavy-light pseudoscalar and vector mesons with improved soft-wall holographic wavefuntions, which take into account the effects of both quark masses and dynamical spins.

The light pseudoscalar Higgs boson in NMSSM [PDF]

open access: yes, 2006
We study the associated production of a very light pseudoscalar Higgs boson with a pair of charginos. The novel signature involves a pair of charged leptons from chargino decays and a pair of photons from the pseudoscalar Higgs boson decay, plus large ...

Primordial gravitational waves for universality classes of pseudoscalar inflation [PDF]

open access: yes, 2016
Current bounds from the polarization of the CMB predict the scale-invariant gravitational wave (GW) background of inflation to be out of reach for upcoming GW interferometers. This prospect dramatically changes if the inflaton is a pseudoscalar, in which
