Searching for Antiproton Decay at the Fermilab Antiproton Accumulator

TL;DR

This paper reports an experimental search for antiproton decay using the Fermilab Antiproton Accumulator, aiming to detect decay if antiprotons have lifetimes under a few hundred thousand years.

Contribution

First experimental search for antiproton decay at Fermilab's Antiproton Accumulator with the APEX setup.

Findings

Sensitivity to antiproton decay if lifetime < 200,000 years

Description of the APEX experimental setup

Data collection and analysis methods for decay detection

Abstract

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.
