Glueballs, hybrids and multiquark states are predicted as bound states in models guided by
quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the …

We discuss theoretical predictions for the existence of exotic (non-quark-model) mesons and
review prominent experimental candidates. These are especially the f0 (1500) and f0 (1710) …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

We show that two nonets and a glueball provide a consistent description of data on scalar
mesons below 1.7 GeV. Above 1 GeV the states form a conventional q bar q nonet mixed …

Glueballs and other resonances with large gluonic components are predicted as bound
states by Quantum Chromodynamics (QCD). The lightest (scalar) glueball is estimated to …

An extensive spectrum of light non-strange qq ̄ states up to a mass of 2400 MeV has
emerged from Crystal Barrel and PS172 data on p ̄ p→ Resonance→ A+ B in 17 final …

We have measured the branching ratio BR (φ→ π0π0γ) with the KLOE detector using a
sample of∼ 5× 107φ decays. φ mesons are produced at DAΦNE, the Frascati φ-factory. We …

We describe the KLOE detector at DAϕNE, the Frascati ϕ, and its physics program. We
begin with a brief description of the detector design and operation. Kaon physics is a major …

We explore the features of Flatté-like parametrizations. In particular, we demonstrate that the
large variation in the absolute values of the coupling constants to the πη (or ππ) and K¯ …

The measurement of the production of f 0 (980) in inelastic pp collisions at s= 5.02 TeV is
presented. This is the first reported measurement of inclusive f 0 (980) yield at LHC …
