Interference pattern analysis in the decays φ → γπη and φ → γπ 0 π 0. Abstract We analyse the interference patterns in the reactions φ → (γa 0 + π 0 ρ) → γπη and φ → (γf 0 +π 0 ρ) → γπ 0 π 0. Taking into account the interference, we fit the experimental data and show that the background reaction does not distort the π 0 η spectrum in the decay φ → γπη everywhere over the energy region and does ...

We study the Λ(1520) resonance in a coupled channel approach involving the πΣ(1385), KΞ(1530), ¯ KN and πΣ channels. Implementing unitarity in coupled channels, we make an analysis of the relative importance of the different mechanisms which contribute to the dynamical structure of this resonance. From experimental information on some partial wave amplitudes and constraints imposed by unitarity...

ar X iv : h ep - e x / 06 03 02 4 v 2 3 1 Ju l 2 00 6 Determining the upper limit of Γ ee for the Y ( 4260 )
By fitting the R values between 3.7 and 5.0 GeV measured by the BES collaboration, the upper limit of the electron width of the newly discovered resonance Y (4260) is determined to be 580 eV/c 2 at 90% C.L. Together with the BaBar measurement on Γee·B(Y (4260) → π + π − J/ψ), this implies a large decay width of Y (4260) → π + π − J/ψ final states.

Belle data for the ππ mass spectrum in X(3872) → π + π − J/Ψ are well fitted by ρ + J/Ψ with J P C = 1 ++ , but are poorly fitted by the ππ S-wave. Formulae for partial wave amplitudes are given for all likely J P C and decay modes of the 3941 MeV peak in ω + J/Ψ. Angular correlations involving up to five angles may allow a spin-parity determination, even with quite low statistics. Special atte...
