Flavour Stability of the Chiral Vacuum and Scalar Meson Dynamics
Previous work relating the flavour variation of the chiral order parameters Fπ, 〈ūu〉 and S-wave scattering data, based on chiral sum rules and chiral perturbation theory at order p, is extended to include O(p) corrections. The finding of a significant decrease of these order parameters, particularly 〈ūu〉, with the number of flavours increasing from NF = 2 to NF = 3 is confirmed, modulo an assum...
متن کاملScalar meson via chiral and crossing dynamics
We show that the non-strange scalar meson, as now reported in the 1996 PDG tables, is a natural consequence of crossing symmetry as well as chiral dynamics for both strong interaction low energy scattering and alsoK ! 2 weak decays.
متن کاملScalar meson dynamics in Chiral Perturbation Theory
A comparison of the linear sigma model (LσM) and Chiral Perturbation Theory (ChPT) predictions for pion and kaon dynamics is presented. Lowest and next-to-leading order terms in the ChPT amplitudes are reproduced if one restricts to scalar resonance exchange. Some low energy constants of the order p ChPT Lagrangian are fixed in terms of scalar meson masses. Present values of these low energy co...
متن کاملOn modeling the scalar meson dynamics with Resonance Chiral Theory
The features of the Resonance Chiral Theory (RχT) related to the description of the lightest scalar resonances, σ , f0(980) and a0(980), are discussed. Major attention is paid to the fits of the invariant mass distributions in the radiative decays of the φ(1020) meson (φ → (γa0 →)γπη and φ → (γ f0/σ →)γππ). The study of the scalar sector in RχT is motivated by the success of the theory predicti...
متن کاملTHE SPINLESS SALPETER EQUATION AND MESON DYNAMICS
Applying the variational method, the spinless reduced Bethe-Salpeter (RBS) equation is solved for the mesonic systems, and the mass spectra are obtained. The method is applied to the Hamiltonian with the Gaussian and hydrogen-type trial wave functions, and different potential models are examined. The results for the different potentials are in challenge in light mesons, while they are consisten...
