Decay of axial-vector mesons into VP and P gamma
TLDR
In this article, a phenomenological Lagrangian for the decay of the SU(3) nonets of the axial-vector mesons of J{sup PC} = 1{sup +-},1{sup ++} into a vector meson and a pseudoscalar constructed with tensor fields for the vector and axial vector mesons was proposed.Abstract:
We propose a phenomenological Lagrangian for the decay of the SU(3) nonets of the axial-vector mesons of J{sup PC}=1{sup +-},1{sup ++} into a vector meson and a pseudoscalar constructed with tensor fields for the vector and axial-vector mesons. The formulation leads to a good reproduction of the different decay branching ratios and assuming vector meson dominance (VMD) it also leads to good results for the radiative decay of the a{sub 1} into pion and photon, and in agreement with the structure proposed in the chiral tensor formulation of radiative decay of axial-vector mesons. The two SU(3) parameters and the mixing angle of K{sub 1A} and K{sub 1B} needed to give the physical K{sub 1}(1270) and K{sub 1}(1400) resonances are also determined.read more

TL;DR: In this article, the authors give a perspective of the theoretical work done recently on the interpretation of results from weak decays into final states that contain interacting hadrons and how it is possible to obtain additional valuable information that is increasing our understanding of hadron interactions and the nature of many hadronic resonances.
