Research on the structure of cosmic-ray electron and positron fluxes in GeV-TeV energy range

摘要

The positron-electron fluxes detected by AMS02, CALET, DAMPE and Fermi-LAT have shown their complex structure which deviated from a single power-law, and the results of DAMPE and Fermi-LAT are obviously higher than those of AMS02 and CALET in 100 GeV-1 TeV range. We point out that the complex positron-electron flux structures can be attributed to two sources with a natural background, and the difference between the two groups of data can be explained in an anomalous bremsstrahlung theory.
