Radiative Decays , Nonet Symmetry and SU ( 3 ) Breaking
We re-examine the problem of simultaneously describing in a consistent way all radiative and leptonic decays of light mesons (V ! P , P ! V , P ! , V ! ee ). For this purpose, we rely on the Hidden Local Symmetry model in both its anomalous and non{anomalous sectors. We show that the SU(3) symmetry breaking scheme proposed by Bando, Kugo and Yamawaki, supplemented with nonet symmetry breaking i...
متن کاملA VMD Based , Nonet and SU ( 3 ) Symmetry Broken Model For Radiative Decays of Light Mesons
We present a VMD based model aiming to describe all radiative decays of light mesons. We show that the SU(3) breaking mechanism proposed by Bando, Kugo and Yamawaki (BKY), supplemented by nonet symmetry breaking in the pseudoscalar sector are sufficient to provide a nice description of all data, except the K radiative width. It is also shown that nonet symmetry breaking has effects which cannot...
متن کاملVMD , the WZW Lagrangian and ChPT : The Third Mixing Angle
We show that the Hidden Local Symmetry Model, supplemented with well-known procedures for breaking flavor SU(3) and nonet symmetry, provides all the information contained in the standard Chiral Perturbation Theory (ChPT) Lagrangian L (0) + L (1). This allows to rely on radiative decays of light mesons (V P γ and P γγ) in order to extract some numerical information of relevance to ChPT: a value ...

متن کاملNonet symmetry and two-body decays of charmed mesons.
The decay of charmed mesons into pseudoscalar (P) and vector (V) mesons is studied in the context of nonet symmetry. We have found that it is badly broken in the PP channels and in the P sector of the PV channels as expected from the non-ideal mixing of the η and the η′. In the VV channels, it is also found that nonet symmetry does not describe the data well. We have found that this discrepancy...
