Pseudoscalar Meson Electroproduction and Tranversity [PDF]

open access: yesExclusive Reactions at High Momentum Transfer IV, 2010
Exclusive meson leptoproduction from nucleons in the deeply virtual exchanged boson limit can be described by generalized parton distributions (GPDs).

ON THE COMPLEXION OF PSEUDOSCALAR MESONS [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
A strongly momentum-dependent dressed-quark mass function is basic to QCD. It is central to the appearance of a constituent-quark mass-scale and an existential prerequisite for Goldstone modes. Dyson-Schwinger equation (DSEs) studies have long emphasised this importance, and have proved that QCD's Goldstone modes are the only pseudoscalar mesons to ...

Decay of the pseudoscalar glueball into scalar and pseudoscalar mesons [PDF]

open access: yesPhysical Review D, 2013
We study a chiral Lagrangian which describes the two- and three-body decays of a pseudoscalar glueball into scalar and pseudoscalar mesons. The various branching ratios are a parameter-free prediction of our approach. We compute the decay channels for a pseudoscalar glueball with a mass of 2.6 GeV, as predicted by Lattice QCD in the quenched ...

Charm meson scattering cross sections by pion and rho meson [PDF]

open access: yes, 2001
Using the local flavor SU(4) gauge invariance in the limit of vanishing vector meson masses, we extend our previous study of charm meson scattering cross sections by pion and rho meson, which is based only on the pseudoscalar-pseudoscalar-vector meson ...

QED effects in the pseudoscalar meson sector [PDF]

open access: yesJournal of High Energy Physics, 2016
We present results on the pseudoscalar meson masses from a fully dynamical simulation of QCD+QED. We concentrate particularly on violations of isospin symmetry. We calculate the $ ^+$-$ ^0$ splitting and also look at other isospin violating mass differences. We have presented results for these isospin splittings in arXiv:1508.06401 [hep-lat]. In this

On the mixing of pseudoscalar mesons

open access: yesPhysics Letters B, 1983
Abstract We calculate the mixing between a glueball and qq pseudoscalars (both the ground state and the first radial excitation) in the framework of the MIT bag model. Our results are large, strongly violate SU(3) and are very sensitive to small changes in the parameters of the model.
