A possible evidence of the gluon condensation effect in cosmic positron and gamma-ray spectra

Abstract

The gluon condensation effect in cosmic proton-proton collisions at high energy is used to explain an excess in the positron spectrum observed by AMS. We find that this excess may originate from the GC-effect in Tycho's supernova remnant.
