Abstract

A search for antiproton decay has been made at the Fermilab Antiproton Accumulator. Limits are placed on fifteen antiproton decay modes. The results are used to place limits on the characteristic mass scale $m_{X}$ that could be associated with $CPT$ violation accompanied by baryon number violation.
