“…cP PRODUCTION IN pp ANNIHILATION AT REST AND THE OZI RULE It has been suggested that an enhanced production of cP mesons could be related to an excess of S8 pairs in the nucleon(122) or to flavor mixing (123-125) with a q 2 q 2 state below threshold containing an 8S pair. Such a state C(1480) (--+ cPnO) was recently reported at Serpukhov(126). If the nucleon and antinucleon do not contain any strange quarks, cP production should be suppressed in pp annihilation by the OZI rule.…”

“…The resonance labeled ρ ′′ , might be the so called C(1480), observed in π − p → φπ 0 n charge-exchange reactions [28], in the same φπ 0 final state. However, a firm conclusion cannot be drawn at the moment; an OZIviolating decay of the meson ρ(1700) [17] cannot be excluded.…”

This paper reports measurements of processes: e + e − → γK− → γφη and e + e − → γφπ 0 . The initial state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to ≈ 4.6 GeV. The overall size of the data sample analyzed is 232 fb −1 , collected by the BABAR detector running at the PEP-II e + e − storage ring. From the Dalitz plot analysis of the K 0 S K ± π ∓ final state, moduli and relative phase of the isoscalar and the isovector components of the e + e − → KK * (892) cross section are determined. Parameters of φ and ρ recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli and phases of theThe cross section for the OZI-forbidden process e + e − → φπ 0 , and the J/ψ branching fractions to KK * (892) and K + K − η are also measured.

“…The Lepton-F collaboration at Serpukhov (Bityukov, 1987) examined the reaction π − p → φπ 0 n with a 32 GeV/c beam. A very strong peak in the cross section was observed near 1500 MeV/c 2 in φπ mass.…”

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
