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

Pseudoscalar pole terms contributions to hadronic light-by-light corrections to the muonium hyperfine splitting [PDF]
, 2002 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.

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

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

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)

Strange and Charm Quark Spins from Anomalous Ward Identity [PDF]
, 2017 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 ...

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

Discovering the Higgs with Low Mass Muon Pairs [PDF]
, 2009 Many models of electroweak symmetry breaking have an additional light pseudoscalar. If the Higgs boson can decay to a new pseudoscalar, LEP searches for the Higgs can be significantly altered and the Higgs can be as light as 86 GeV. Discovering the Higgs
