Abstract
We demonstrate the advantages of the wavelet analysis (WA) for
resolving the structures in experimental data on
e+e-
annihilation into hadron states with quantum numbers of
meson. The WA yields a useful set of starting conditions for
analysis of
states with multiresonance unitary
Breit-Wigner method. We also apply the WA for the ratio
