Resonances in weak nonleptonic Omega(-) decay
Weak resonance chiral perturbation theory the decay of the amplitude and resonance
2014/12/22
We examine the importance of JP=1/2+,1/2- resonances for weak nonleptonic Ω- decays within the framework of chiral perturbation theory. The spin-1/2 resonances are included into an effective theory an...
We determine the value of the omega -rho- pi mesons coupling (g_{omega rho pi}), in the context of the vector meson dominance model, from radiative decays, the omega -> 3 pi decay width and the e^+e^-...
