Abstract
The master formula approach to chiral symmetry breaking is used to analyze the phase shifts for scattering in the elastic region. The results are in excellent agreement with the data for the phase shifts up to the K-K bar threshold. Our analysis shows that the pi-pi data near threshold in the scalar channel favors a large quark condensate in the vacuum, i.e. <q bar q> \sim -(240 MeV)^3.
