“…For example, a relatively narrow peak in the σ region is seen in the J/ψ → ppπ + π − decay [281] with a shoulder in the ρ(770) region. A good description of this process within the coupled channel ChUA was obtained in [282] including an apparently narrower σ.…”

From controversy to precision on the sigma meson: A review on the status of the non-ordinary f0(500) resonance

The existence and properties of the sigma meson have been controversial for almost six decades, despite playing a central role in the spontaneous chiral symmetry of QCD or in the nucleonnucleon attraction. This controversy has also been fed by the strong indications that it is not an ordinary quark-antiquark meson. Here we review both the recent and old experimental data and the model independent dispersive formalisms which have provided precise determinations of its mass and width, finally settling the controversy and leading to its new name: f 0 (500). We then provide a rather conservative average of the most recent and advanced dispersive determinations of its pole position √ s σ = 449 +22−16 −i(275±12). In addition, after comprehensive introductions, we will review within the modern perspective of effective theories and dispersion theory, its relation to chiral symmetry, unitarization techniques, its quark mass dependence, popular models, as well as the recent strong evidence, obtained from the QCD 1/N c expansion or Regge theory, for its non ordinary nature in terms of quarks and gluons.

“…However, the MarkII collaboration first published experimental results showing that a large SU(3) flavor symmetry breaking takes place in the J/ψ decays into baryon pairs [533], especially, into octet-decuplet baryon pairs. This was confirmed by the DM2 [534] and MarkIII [535] collaborations.…”

There has recently been a dramatic renewal of interest in the subjects of hadron spectroscopy and charm physics. This renaissance has been driven in part by experimental reports of D 0 D 0 mixing and the discovery of narrow D sJ states and a plethora of charmonium-like XY Z states at the B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESII. At the same time, lattice QCD is now coming of age, and we are entering a new era when precise, quantitative predictions from lattice QCD can be tested against experimental measurements. For example, the High Precision QCD (HPQCD) and United Kingdom QCD (UKQCD) collaboration's recent high-precision, unquenched calculation of f D + = 208 ± 4 MeV has been found to agree with the CLEO-c collaboration measurement of f D + = 223± 17 ± 8 MeV -a precision level of ∼ 8%. Intriguingly, this agreement does not extend to f D s , where the HPQCD + UKQCD result f D s = 241±3 MeV is more than three standard deviations below the current world average experimental value f D s = 276 ± 9 MeV. Precision improvements, especially on the experimental measurements, are called for and will be of extreme interest.The BES-III experiment at BEPCII in Beijing, which will start operation in summer 2008, will accumulate huge data samples of 10 × 10S -pairs per running year, respectively, running in the τ -charm theshold region. Coupled with currently available results from CLEO-c, BES-III will make it possible to study in detail, and with unprecedentedly high precision, light hadron spectroscopy in the decays of charmonium states and charmed mesons. In addition, about 90 million DD pairs will be collected at BES-III in a three-year run at the ψ(3770) peak. Many high precision measurements, including CKM matrix elements related to charm weak decays, decay constants f D + and f D S , Dalitz decays of three-body D meson decays, searches for CP violation in the charmed-quark sector, and absolute decay branching fractions, will be accomplished. This physics book provides detailed discussions on important topics in τ -charm physics that will be explored during the next few years at BES-III . Both theoretical and experimental issues are covered, including extensive reviews of recent theoretical developments and experimental techniques. Among the subjects covered are: innovations in Partial Wave Analysis (PWA), theoretical and experimental techniques for Dalitz-plot analyses, analysis tools to extract absolute branching fractions and measurements of decay constants, form factors, and CP -violation and D 0 D 0 -oscillation parameters. Programs of QCD studies and near-threshold tau-lepton physics measurements are also discussed.
