This paper describes an experimental search for antiproton decay at the Fermilab Antiproton Accumulator. The E868 (APEX) experimental setup is described. The APEX data is expected to be sensitive to antiproton decay if the antiproton lifetimes is less than a few times 100 000 years. 1 Introduction  There has been a considerable experimental effort devoted to the search for proton decay. As a result we know that the proton lifetime ø p  O(10  32  ) years. The CPT theorem requires that the proton and p lifetimes are equal. A search for p decay with a short lifetime (ø p ! ø p ) tests the CPT theorem and the intrinsic stability of antimatter. Although we have no deep theoretical reason to suspect CPT violation we note that p decay with a short lifetime would provide a natural although unconventional explanation for baryogenesis. In the past there have been a number of experimental searches for the decay of antiprotons stored in ion traps or storage rings. The most sensitive results to dat..
