The case of the pseudoscalar glueball
AIP Conference Proceedings, 2006The η(1405), once called the E or ι represents a case in itself in the glueball search. It has been studied through six different production mechanisms by more than thirty experiments for a period spanning four decades. More than 70 experimental results are now quoted within the Review of Particle Properties.

A model for pseudoscalar-pseudoscalar scattering and production
Nuclear Physics B - Proceedings Supplements, 1991Abstract We present results from a coupled-channel quark model analysis of light-quark S-wave pseudoscalar-pseudoscalar scattering and production processes. Annihilation mixing to s-channe qq scalar resonances and quark exchange interactions are found to be important contributions to the dynamics of these processes. Contributions from the exchange of

Chiral Lagrangian of pseudoscalars and vectors
Physical Review D, 1985We formulate a parity-invariant chiral Lagrangian which includes nonlinearly transforming vector mesons but no axial-vector mesons. It is gotten by a simple substitution from the Lagrangian involving a linearly transforming vector and axial-vector multiplet.

Exclusive decays of a heavy pseudoscalar
Physical Review D, 1986Branching ratios for two exclusive decay modes of a hidden-heavy-flavor pseudoscalar meson into other heavy mesons are calculated from quantum chromodynamics in lowest-order perturbation theory. Heavy mesons are treated as nonrelativistic quark-antiquark bound states. All parameters are fixed by hadronic and leptonic widths.

Low energy pseudoscalar-pseudoscalar interactions in the nonrelativistic quark model
AIP Conference Proceedings, 1991We give a brief introduction to the nonrelativistic quark model and then present results from a coupled‐channel quark model analysis of light‐quark S‐wave pseudoscalar‐pseudoscalar scattering and production processes. Annihilation mixing to s‐channel qq scalar resonances and quark exchange interactions are found to be important.

Scalar and pseudoscalar charges
American Journal of Physics, 1976The interaction of a ’’scalar’’ charge es (even under T) and a ’’pseudoscalar’’ charge ep (odd under T) is investigated in the framework of classical mechanics. We show that the most general force consistent with the conservation of linear momentum and angular momentum is F=esep(r×v)/cr3, where c is a constant.

Duality and the pseudoscalar mesons
Il Nuovo Cimento A, 1976The Lovelace-Veneziano model for the pseudoscalar-meson process PP → PP is considered with particular attention to the problematical requirement of ideal mixing for the pseudoscalar nonet. A solution to the problem which retains the narrow-resonance approximation for this process is found.

It is shown that a true pseudoscalar charge density—a ψ*ψ which has opposite signs in two regions—can exist. This fact is accomplished by allowing a parity transformation, for which p*p = −1, and by making the operation of hermitian adjoint differ by a minus sign in the two regions.
