TL;DR: A search for cosmic-ray antideuterons using data collected during four BESS balloon flights from 1997 to 2000 found no candidate and derived an upper limit of 1.9 x 10(-4) (m2s sr GeV/nucleon)(-1) for the differential flux at the top of the atmosphere.

TL;DR: In nine flights between 1993 and 2002, the Balloon Borne Experiment with a Superconducting Spectrometer (BESS) has measured the energy spectrum of cosmic-ray antiprotons between 0.18 and 4.20 GeV, and the spectra of protons and helium to several hundred GeV as discussed by the authors.
