Abstract

The normal and anomalous chiral Ward identities are reexamined from the point of view of chiral and 1/ perturbation theory. Constraints of psi ..-->.. eta ..gamma.. and psi ..-->.. eta' ..gamma.. and pseudoscalar two photon decays are imposed, yielding a system of six simultaneous equations. A solution for the pseudoscalar decay constants is found which is relatively insensitive to the unknown gluonic bound states. The decay eta ..-->.. 3..pi.. is then calculated using these results, with good agreement with recent measurements.

Pseudoscalar decay constants and eta. -->. 3. pi. in chiral and 1/N perturbation theory

Journal Article Milton, K; Palmer, W; Pinsky, S - Phys. Rev., D; (United States)

The normal and anomalous chiral Ward identities are reexamined from the point of view of chiral and 1/N perturbation theory. Constraints of psi..-->..eta..gamma.. and psi..-->..eta'..gamma.. and pseudoscalar two-photon decays are imposed, yielding a system of six simultaneous equations. A solution for the pseudoscalar decay constants is found which is relatively insensitive to the quantum-chromodynamic surface term. The decay eta..-->..3..pi.. is then calculated using these results, with good agreement with recent measurements.

Chiral Ward identities for the pseudoscalar mesons including the gluonic bound state G(1440)

Journal Article Milton, K; Palmer, W; Pinsky, S - Phys. Rev. D; (United States)

We reanalyze the chiral Ward identities for the pseudoscalar mesons including the recently identified glueball state G(1440), in the hope that the solution for the decay constants will shed light on the interpretation of G(1440) as a gluonic bound state. Even when supplemented with experimental rates for (psi..-->..eta'..gamma..)/(psi..-->..eta..gamma..) and (eta'..--> gamma gamma..)/(eta..--> gamma gamma..)/(..pi../sup 0/+..gamma gamma..) we cannot obtain definite predictions for the pseudoscalar decay constants and for G..--> gamma gamma.., because the solutions are exceedingly sensitive to poorly known parameters. Classes of solutions are presented, which are functions of B(G..-->..KK-bar..pi..); a solution is only possible if B(G..-->..KK-bar..pi..)< or =30%.more »« less

Pseudoscalar glueball mass from {eta}-{eta}{sup '}-G mixing

Journal Article Haiyang, Cheng; Hsiangnan, Li; Liu, K - Physical Review. D, Particles Fields

We deduce the mass of the pseudoscalar glueball G from an {eta}-{eta}{sup '}-G mixing formalism based on the anomalous Ward identity for transition matrix elements. With the inputs from the recent KLOE experiment, we find a solution for the pseudoscalar glueball mass around (1.4{+-}0.1) GeV, which is fairly insensitive to a range of inputs with or without Okubo-Zweig-Iizuka-rule violating effects. This affirms that {eta}(1405), having a large production rate in the radiative J/{psi} decay and not seen in {gamma}{gamma} reactions, is indeed a leading candidate for the pseudoscalar glueball.

Quark-glue structure of the eta and eta' mesons, with application to psi. -->. eta (eta'). gamma. and psi'. -->. psieta

Journal Article Goldberg, H - Phys. Rev. Lett.; (United States)

A careful analysis of the Ward identities involving the axial divergences partial/sup ..mu../A..mu.., combined with a fit to the 2..gamma.. decays of the ..pi../sup 0/, eta, and eta' via the quantum electrodynamic anomaly, allows a consistent description of the pseudoscalar nonet with zero (or small) quantum chromodynamic surface term. The gluonic matrix elements < 0 vertical-bar FF vertical-bar P > of the eta and eta' obtained from the Ward identities lead to a good quantitative understanding of the relative rates (psi ..-->.. eta'..gamma..)/(psi ..-->.. eta..gamma..), and a qualitative understanding of the nonsuppression of psi' ..-->.. psieta.

Two-photon decay of the pseudoscalar glueball

Journal Article Senba, K; Tanimoto, M - Phys. Rev. D; (United States)

We derive two sum rules for the amplitudes for two-photon decays of the pseudoscalar mesons including a glueball. The two-photon decay width of the pseudoscalar glueball can be estimated with inputs of GAMMA(..pi -->..2..gamma..), GAMMA(eta..-->..2..gamma..), and GAMMA(eta'..-->..2..gamma..), assuming Ward identities and two other conditions to be useful. If the E(1440) seen in the radiative decay of J/psi is the pseudoscalar glueball, then we obtain GAMMA(E..-->..2..gamma..) = 10 +- 26 keV, where the large error comes mainly from the experimental ambiguity of GAMMA(eta'..-->..2..gamma..).
