The gluon condensation effects in the DAMPE cosmic ray spectrum of electrons and positrons

TL;DR

This paper explores how gluon condensation in protons at ultra high energies can explain features in the DAMPE cosmic ray electron and positron spectrum, suggesting a new particle physics effect influences cosmic ray observations.

Contribution

It introduces the concept that gluon condensation effects in protons can account for observed spectral breaks in cosmic ray data, linking particle physics with astrophysical phenomena.

Findings

Gluon condensation can produce spectral breaks at ~0.9 TeV and 3-4 TeV in cosmic ray spectra.

The observed features in DAMPE data are consistent with gluon condensation effects.

Gluon condensation influences the secondary particle production in high-energy cosmic ray collisions.

Abstract

Gluons dominate the proton behavior at high energy collisions, they can be condensed at ultra high energy. The collisions of the accelerated high energy protons with interplanetary matter in cosmic rays will produce a huge number of secondary particles at the gluon condensate energy region, which break the primary power-law of cosmic rays. The above predictions seem to be consistent with the recent DAMPE data concerning the electron plus positron spectra. We find that the smoothly broken power-law at $\sim 0.9 TeV$ and $3\sim 4 TeV$ in the DAMPE data can be understood as the gluon condensation effects in proton.
