Anisotropy of Positron and Electron Fluxes Measured with the Alpha Magnetic Spectrometer on the ISS

A measurement of the cosmic ray anisotropy on the arrival directions of elementary particles electrons and positrons has been performed in galactic coordinates by the Alpha Magnetic Spectrometer onboard the International Space Station. The analysis is based on the sample of events collected in the first 9 years of data taking. Results are consistent with isotropy and upper limits at the 95% C.I. on the dipole amplitude have been established. In particular, for energies above 16 GeV limits of 𝛿 < 0.36% and 𝛿 < 1.65% are obtained for electrons and positrons respectively.
