Pseudoscalar glueball mass: a window on three-gluon interactions

European Physical Journal A, 2019
In pure-glue QCD, gluon–gluon scattering in the $$J^{PC}=0^{-+}$$ J PC = 0 - + channel is described by a very simple equation, especially if one considers just the leading contribution to the scattering kernel.

Chiral Lagrangian of pseudoscalars and vectors

Physical Review D, 1985
We 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, 1986
Branching 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, 1991
We 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, 1976
The 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, 1976
The 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.

Pseudoscalar charge density

Canadian Journal of Physics, 1969
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.
