A sensitive search for direct CP violation in E-(E+) and A (3,) decays is underway at FNAL. Experiment E871 (HyperCP) intends to perform a precision measurement of the angular distribution of protons (anti-protons) with respect to the helicity axis in the rest frame of the A (/k). The slopes of thes

HyperCP (E871), a Fermilab experiment searching for CP violation in ~. and A hyperon decays, finished its first data taking run at the end of 1997, and accumulated over one billion --and -~+ decays. A sensitivity of approximately 2x10 -4 in A-A = (a=\_aA --a~a-K)/(a=\_aA + a=--aX) is expected. A non
