TL;DR: In this paper, an overview of the increase of experimental knowledge of mesons which are built by light quarks is given, including those mesonic states containing gluons and those with an exotic internal quark structure such as qq-qq.

TL;DR: In this article, the SU(3) flavour structure of ι(1460) is exploited to seek consistency between vector meson dominance and anomalous Ward identities, and it is shown that a minimum of 10 to 20% breaking in nonet symmetry is necessary to get an overall fit with the radiative rates of low-lying η and η′.

TL;DR: In this article, a new theory of strong interactions is proposed based on the notion of parity conservation in strong couplings, which is similar to the one proposed in this paper, but with three different types of couplings: hypercharge coupling, isospin coupling, and isobarsin coupling.

TL;DR: In this article, high-energy photon interactions are discussed in terms of the hadronic structure of the photon, which is expressed by means of a formulation which is akin to, but somewhat more general than, vector-meson-dominance or specific generalized vectordominance models.
Abstract: High-energy photon interactions are discussed in terms of the hadronic structure of the photon, which is expressed by means of a formulation which is akin to, but somewhat more general than, vector-meson-dominance or specific generalized vector-dominance models. Experiments which demonstrate and yield information about this hadronic structure are discussed critically, and the resulting information is carefully evaluated. Special attention is paid to diffractive processes such as the photoproduction of vector mesons and to photon shadowing effects on nuclei. Relationships to other views of photon interactions, such as the parton model and the space-time description, are also discussed; these views are seen to complement the hadronic structure picture rather than to be in conflict. The general overview is that there is ample evidence which shows that the photon's hadronic structure plays a significant role in its interactions. What further work would most significantly enhance the understanding of the hadronic structure of the photon is also pointed out.

TL;DR: In this paper, it was shown that there are at least two states near 1.4 GeV which decay to a pseudoscalar, one being an axial vector and the other being a glueball.
Abstract: Evidence is presented that there are at least two states near 1.4 GeV which decay to $$\overline{K}$$Kπ. One is E(l420), an axial vector, and the other is G(l440), probably a pseudoscalar. The pseudoscalar is likely to be a glueball.
