Abstract
It is shown that the small ππ scattering lengths as predicted by current algebra can be well consistent with the recent ππ phase shift analysis, the forward dispersion relation and the sum rule for the axialvector coupling constant, if one properly takes into account a zero in each of the S-wave amplitudes.Keywords
