Abstract

We present data on 3652 analyzed events of the reaction π^-p → φφn at 22 GeV/c. A partial wave analysis has been performed on the φφ system. The results are well represented by three resonances all with quantum numbers I^GJ^PC = 0⁺2⁺⁺. The absence of the Okubo-Zweig-Iizuka suppression observed in this reaction, the selection of only three J^PC=2⁺⁺ states (g_T, g_T′, and g_T″) which comprise virtually all of the cross section, and the large φφn signal over a very different φK⁺K^-n background are all well explained if these states are produced by 1–3 glueballs (i.e. multigluon resonances).

Light hadron spectroscopy at BESIII

$J / ψ (ψ 3686)$ decay is an ideal place to study light hadron spectroscopy. BESIII has collected the largest $J / ψ, ψ (3686)$ samples in the world, including 1.31 billion $J / ψ$ events and 0.5 billion $ψ (3686)$ events. In this paper, latest experimental results at BESIII about the $p \overline{p}$ mass threshold enhancement and $X (1835)$ are presented, which help us to understood the nature of the states around 1.8 GeV. Results of a model independent partial wave analysis of $J / ψ \to γ π^{0} π^{0}$ and a partial wave analysis of $J / ψ \to γ ϕ ϕ$ are also presented, which may contribute to the search for possible scalar, pseudoscalar or tensor glueballs. More experimental results about light hadron spectroscopy at BESIII are expected.
