Description

It is shown that the processes e+e->>π+π- and τ>>ππν can be described in a unified approach in satisfactory agreement with experiment using the vector coupling constant g= 6. In this case, in addition to quark loops, it is also necessary to take into account meson loops corresponding to the next order in 1/Nc. These loops must be taken into account when describing the γ(W)>>ρ transition, as well as in interaction of mesons in the final state.
