“…It might be plausible to argue that these two states are in fact significant mixtures of the scalar glueball and the ss member of the 0 ++ nonet. These states were confirmed in a subsequent experiment at Serpukhov (Bolonkin, 1988). In fact, a reanalysis of this data, in combination with the data from both LASS and J/ψ radiative decay (Lindenbaum and Longacre, 1992), shows clearly that J = 0 and derives branching ratios to ππ, KK, and ηη.…”

We survey the current status of light meson spectroscopy. We begin with a general introduction to meson spectroscopy and and its importance in understanding the physical states of Quantum Chromo Dynamics (QCD). Phemenological models of hadron spectroscopy are described with particular emphasis on the constituent quark model and the qualitative features it predicts for the meson spectrum. We next discuss expectations for hadrons lying outside the quark model, such as hadron states with excited gluonic degrees of freedom. These states include so-called hybrids and glueballs, as well as multiquark states. The established meson states are compared to the quark model predictions and we find that most meson states are well described by the quark model. However, a number of states in the light-quark sector do not fit in well, suggesting the existence of hadronic states with additional degrees of freedom. We end with a brief description of future directions in meson spectroscopy.2

“…A small peak has been observed at 1750 MeV for J = 0 in two sets of data on ππ → K S K S [11,12]. Secondly, a partial wave analysis of J/ψ → γ(4π) has fitted 4π peaks at 1780 MeV with J = 0 [13].…”

“…The experimental status of f J is reported in Ref. [19], where its evidence comes from the Mark III collaboration [20] and the BES collaboration [21], also being supported by π − (K − ) p collisions [22][23][24]. However, the direct confirmations from pp collisions [25,26] and 2γ processes [27,28] are inconclusive.…”

We study the hadronicB 0 s decays based on the existence of the resonant state f J (2220). In particular, we are able to explain the unexpected large experimental result of B(B 0 s → J/ψ pp) = (3.0 +1.2 −1.1 ± 0.52 ± 0.03) × 10 −6 measured recently by the LHCb collaboration due to the resonant contribution inB 0 s → J/ψ f J (2220) with f J (2220) → pp, while it is estimated to be at most of order 10 −9 in terms of the OZI rule without the resonance. In addition, we find that B(B 0 s → D * 0 (f J →) pp) = (4.70 ± 2.89) × 10 −7 , B(B 0 s → J/ψ(f J →)ππ) = (15.6 ± 15.2) × 10 −6 , and B(B 0 s → D * 0 (f J →)ππ) = (24.5 ± 24.4) × 10 −7 , while B(B 0 s → J/ψ(f J →)KK) < 1.6 × 10 −5 and B(B 0 s → D * 0 (f J →)KK) < 2.5×10 −6. Moreover, we predict that the decay branching ratios ofB 0 s → (J/ψ, D * 0) ¯ are (2.68 ± 1.23) × 10 −7 and (2.25 ± 0.80) × 10 −6. Some of the predictedB 0 s decays are accessible to the experiments at the LHCb.
