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…
Mesonic interactions and their contribution to strong phases in flavor physics
B. El-Bennich, A. Furman, R. Kaminski +3
We analyze the contributions of hadronic final-state interactions to the strong phases generated in the B -> Kpipi weak decays. To this end, we develop an alternative approach to t…
CP violation and final state interactions in B --> K pi pi decays
L. Lesniak, B. El-Bennich, A. Furman +3
Effects of CP violation and of final state interactions between pairs of pseudoscalar mesons are studied in three-body B+, B-, B0 and antiB0 decays into K pi pi. An alternative app…
The antinucleon-nucleon quasi-bound states: J/psi and atomic evidence
S. Wycech, B. Loiseau
The measurements of J/psi decays into photon, proton and antiproton show a strong enhancement at the proton-antiproton threshold not seen in the decays into neutral pion, proton an…
Application of Roy's equations to analysis of pion-pion experimental data
B. Loiseau, R. Kaminski, L. Lesniak
The scalar-isoscalar, scalar-isotensor and vector-isovector pion-pion partial wave amplitudes are analyzed. Preliminary results indicate that only the scalar-isoscalar amplitude fi…
Peculiarities in multichannel interaction amplitudes for meson-meson scattering and scalar meson spectroscopy
R. Kaminski, L. Lesniak, B. Loiseau
Interactions in coupled channels pipi, KKbar and an effective 2pi2pi in scalar-isoscalar wave have been analysed. Influence of interchannel couplings on analytical structure of mul…
