Scalar resonances in a unitary -wave model for
D. R. Boito, J. -P. Dedonder, B. El-Bennich +2
We propose a model for decays following experimental results which indicate that the two-pion interaction in the -wave is dominated by the scalar resonance…
The Scalar Meson f0(980) in Heavy-Meson Decays
B. El-Bennich, O. Leitner, J. -P. Dedonder +1
A phenomenological analysis of the scalar meson f0(980) is performed that relies on the quasi-two body decays D and Ds -> f0(980)P, with P=pi, K. The two-body branching ratios are…
The Ground Scalar Nonet and D Decays
Olivier Leitner, Benoit Loiseau, Jean-Pierre Dedonder +1
A short review on light scalar mesons is performed both in experiment and theory. A naive model, constrained by D branching ratios, is derived in order to make predictions on the w…
Scalar meson properties from D-meson decays
B. El-Bennich, O. M. A. Leitner, B. Loiseau +1
Decay amplitudes of D(D_s)->f0(980)X, X=pi, K, are compared to experimental branching ratios with the aim of singling out the poorly known D->f0(980) transition form factor in thes…
Pseudoscalar-scalar transition form factors in covariant light front dynamics
O. M. A Leitner, B. El-Bennich, B. Loiseau +1
In an explicitly covariant light-front formalism, we analyze transition form factors between pseudoscalar and scalar mesons. Application is performed in case of the $B \to f_0(980)…
