Radiative decays with a0(980) and f0(980) from ChPT at order p^4
S. Ivashyn, A. Korchin
A consistent description of the pi0 pi0 invariant mass distribution in the phi(1020) -> f0(980) gamma -> pi0 pi0 gamma decay and the pi0 eta in phi(1020) -> a0(980) gamma -> pi0 et…
$D^+ \to K^- \p^+ \p^+ $: the low-energy sector
D. R. Boito, P. C. Magalhães, M. R. Robilotta +1
An effective chiral lagrangian, which includes scalar resonances, is used to describe the process $D^+ \rar K^- \p^+ \p^+$ at low-energies. Our main result is a…
New formula for a resonant scattering near an inelastic threshold
L. Lesniak
We show that the Flatte formula is not adequate to interpret precision data on a resonance production near an inelastic threshold. A unitary parameterization, satisfying generalize…
Review of Scalar Mesons
D. V. Bugg
The formulae needed to parametrise sigma, kappa, a0(980) and f0(980) are reviewed. For sigma and kappa, the Adler zero due to Chiral Symmetry Breaking plays a crucial role. The f0(…
The Light Scalar Mesons a_0/f_0(980) at COSY-Juelich
M. Buescher
The light scalar mesons a_0/f_0(980) are being investigated at COSY-Juelich by detecting the strong decays into K-K-bar and pi-eta/pi-pi as well as radiative decays into vector mes…
The complex relation between production and scattering amplitudes
Eef van Beveren, George Rupp
The unitarity relation, Im(A)=T* A, is derived for a three-body production amplitude, A, that consists of a complex linear combination of elements of the two-body scattering amplit…
