Abstract
A search for antiproton decay has been made at the Fermilab Antiproton Accu mulator. Limits are placed on 13 antiproton decay modes. The results includ e the first explicit experimental limits on the muonic decay modes of the a ntiproton, and the first limits on the decay modes e(-)gamma gamma and e(-) omega. The most stringent limit is for the decay mode (p) over bar --> e(-) gamma. At 90% C.L. we find that tau(p)(-)/B((p) over bar --> e(-)gamma) > 7 X 10(5) yr. The most stringent limit for decay modes with a muon in the fi nal state is for the decay (p) over bar --> mu(-)gamma. At 90% C.L. we find that tau(p)(-)/B((p) over bar --> mu(-)gamma) > 5 X 10(4) yr.
