====== Positron excess ======

A 'Positron Excess' in cosmic emissions from deep space have recently been logged by various observation satellites ( PAMELA, Fermi-LAT and AMS-02 ).

As yet, there is no agreed explanation for the source of the positrons (i.e. 'anti' electrons ) in the numbers in which they are found.

There are (at least ) three current theories - some of which are contradictory. See: [ all papers are from //arXiv// ] \\
