Ratio of strange to non-strange quark condensates in QCD
Laplace transform QCD sum rules for two-point functions related to the
strangeness-changing scalar and pseudoscalar Green's functions and
, are used to determine the subtraction constants and
, which fix the ratio .
Our results are ,
, and . This implies corrections to
kaon-PCAC at the level of 50%, which although large, are not inconsistent with
the size of the corrections to Goldberger-Treiman relations in .Comment: Latex file, 14 pages including 3 figure
