Descripción
AMS-02 is a large acceptance cosmic ray detector which has been installed in the International Space Station ISS in May 2011, where it is collecting cosmic rays up to TeV energies.
A primary cosmic ray research topic is the search for Dark Matter indirect signatures in the lepton fluxes. AMS-02 is providing cosmic lepton data with an unprecedented precision.
Such a physics goal has been achieved thanks to the large hadron/lepton separation power obtained combining the independent measurements from the TRD, ECAL and Tracker detectors.
In this contribution we will detail the analysis techniques used to distinguish leptons from the hadronic background and show the in-flight performances of these detectors relevant for the electron/positron measurements.
