Quark and gluon content of the neutral tensor mesonsf-f′-θ

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A careful analysis of the available data on thef,f′ and θ mesons is carried out. It is shown that a coherent mixing scheme for these three mesons is not ruled out by the present data. Several consequences and predictions from this scheme are presented and, in particular, a new methodology for testing the validity of the flavour independence hypothesis for tensor glueball decays is discussed. The ambiguities left open by the present analysis call for better data in “conventional” spectroscopy. In particular, a better knowledge of the γγ, ππ and\(K\bar K\) decay modes of tensor mesons would help very much in clarifying the tensor glueball picture.
