Strange and Charm Quark Spins from Anomalous Ward Identity [PDF]
We present a calculation of the strange and charm quark contributions to the nucleon spin from the anomalous Ward identity (AWI). It is performed with overlap valence quarks on 2+1-flavor domain-wall fermion gauge configurations on a $24^3 \times 64 ...

Pseudoscalar pole terms contributions to hadronic light-by-light corrections to the muonium hyperfine splitting [PDF]
The contribution of pseudoscalar pole diagrams to the hadronic light-by-light corrections of order alpha^3 E_F to the ground state hyperfine splitting in hydrogenic atom is calculated in the pseudoscalar pole terms approximation.

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

The light pseudoscalar Higgs boson in NMSSM [PDF]
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 ...

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

SCALAR AND PSEUDOSCALAR GLUEBALLS [PDF]
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)

Collider constraints on light pseudoscalars [PDF]
Abstract We investigate the bounds on light pseudoscalars that arise from a variety of collider searches. Special attention is thereby devoted to the mass regions [3, 5] GeV and [9, 11] GeV, in which a meaningful theoretical description has to include estimates of non-perturbative effects such as the mixing of the pseudoscalar with
