Description
The positron flux measured by the Alpha Magnetic Spectrometer in the TeV region exhibits complex energy dependence. It is described by the sum of a term associated with the positrons produced in the collision of cosmic rays, which dominates at low energies, and a new source term, which dominates at high energies and is associated with either dark matter or astrophysical origin. The positron source term also manifests itself in the measured electron spectrum. This is the first indication of the existence of identical charge symmetric source term both in the positron and in the electron spectra and, as a consequence, the existence of new physics.
