Fermilab experiment E871, HyperCP, is designed
to search for evidence of direct CP violation
in Cascade and Lambda hyperon decays. The asymmetry
of the angular decay distribution of proton in the Lambda
helicity frame between Cascade(-) -> Lambda + pi(-), Lambda -> p, pi(-)
and the charge-conjugate decays, will be measured. During
the 1997 and 1999 fixed target runs at Fermilab HyperCP collaboration
collected billions of Cascade and anti-Cascade decays that would allow
to probe this asymmetry at the 10^-4 statistical level. The status
of the data analysis will be described.
