- Abstract
Generalized Hidden Local Symmetry (GHLS) model as the chiral model of pseudoscalar, vector, and axial vector mesons, is confronted the ALEPH data on the decay τ− → π+π−π−ντ. It is shown that the spectrum of this decay in GHLS falls short of the experimental data. The modifications of GHLS based on inclusion of heavier axial vector mesons are studied. It is shown that the scheme with two additional axial vector isovector mesons with masses m a = 1.59 GeV and m a = 1.88 GeV gives a good description of the ALEPH data.
