Abstract

Using the leaky-box model the upper limit of the antiproton-proton flux ratio at the top of the atmosphere has been estimated from the latest primary nucleon spectrum and accelerator data on\(pp \to \bar pX\) inclusive reactions. The estimated value of\(\bar p/p\) flux ratio comes out to be (3.6±0.3)×10−4 is in accord with the previous results but still far from the measurements.
