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…
Alpha-Alpha scattering, chiral symmetry and 8Be lifetime
E. Ruiz Arriola
Alpha-alpha scattering is discussed in terms of a chiral two pion exchange potential which turns out to be attractive and singular at the origin, hence demanding renormalization. W…
