Cosmic ray antiprotons and the single source model

In view of the fact that the AMS-02 instrument has recently been used to make preliminary observations of the ratio of the antiprotons ( ) to protons (P) in the primary cosmic radiation we have returned to our idea of signatures of a local recent supernova. We find that at the present level of accur...

Description
Summary:In view of the fact that the AMS-02 instrument has recently been used to make preliminary observations of the ratio of the antiprotons ( ) to protons (P) in the primary cosmic radiation we have returned to our idea of signatures of a local recent supernova. We find that at the present level of accuracy there is no inconsistency between our predicitions for the ratio to some hundreds of GeV using the preliminary observations.
