Scalar f 0 ( 980 ) and σ ( 500 ) meson exchange in φ decays into π 0 π 0 γ
The complementarity between Chiral Perturbation Theory and the Linear Sigma Model is exploited to study π0π0 production in φ radiative decays, where the effects of the f0(980) scalar resonance, and those of its more controversial σ(500) partner, should manifest via the φ → K+K−(γ) → π0π0γ decay chain. The recently reported data on φ → π0π0γ coming from the VEPP-2M e+e− collider in Novosibirsk a...
متن کاملMeson loops in the f 0 ( 980 ) and a 0 ( 980 ) radiative decays into ρ , ω
Meson loops in the f 0 (980) and a 0 (980) radiative decays into ρ, ω Abstract. We calculate the radiative decay widths of the a0(980) and f0(980) scalar mesons into ργ and ωγ considering the dynamically generated nature of these scalar resonances within the realm of the Chiral Unitary Approach. The main ingredient in the evaluation of the radiative width of the scalar mesons are the loops comi...
متن کاملf 1 ( 1285 ) decays into a 0 ( 980 ) π 0 , f 0 ( 980 ) π 0 and isospin breaking
Abstract We evaluate the decay width for the processes f1(1285)→ πa0(980) and f1(1285)→ πf0(980) taking into account that all three resonances are dynamically generated from the meson-meson interaction, the f1(1285) from K ∗K̄ − c.c and the a0(980), f0(980) from πη,KK̄ and ππ,KK̄ respectively. We use a triangular mechanism similar to that of the η(1405) → ππη, which provides a decay width for f1(1...

متن کامل/ 02 08 03 9 v 1 2 3 A ug 2 00 2 Light Scalar Mesons σ ( 500 ) , f 0 ( 980 ) and κ in Charm Meson Decays 1
We present recent results on scalar light mesons based on Dalitz plot analyses of charm decays from Fermilab experiment E791. Scalar mesons are found to have large contributions to the decays studied, D + → K − π + π + and D + , D + s → π − π + π +. From the first decay, we find good evidence for the existence of the light and broad κ meson and we measure its mass and width. We find strong evid...
