TLDR
In this article, the authors considered the possibility of the existence of charmonium-four-quark states to explain the recently observed anomalies in psi decays and showed that the photoproduction cross-section appears to give a reasonable signal for the production of the choronium-pion state.Abstract:

TL;DR: In this article, the spectra and dominant decay couplings of mesons are calculated in the quark-bag model and shown to be broad, heavy, and usually inelastic in formation processes.

TL;DR: In this paper, a quark-bag model of light, colored, and permanently confined quarks gauge-coupled to non-Abelian colored gluons is proposed for estimating the masses and decay couplings of multiquark hadrons.

TL;DR: In this paper, it is proposed that these anomalies are caused by the mixing of ground-state isoscalar vector mesons with a vector glueball, which was first postulated by Freund and Nambu in 1975.

TL;DR: In this paper, it was shown that photoproduction in particular appears to give a reasonable signal for the production and decay of a vector in the state of polygonal vectors.
