Following the pioneering experiments (ATIC, BESS, CREAM, HEAT, PAMELA, …), using a magnetic spectrometer (AMS) on ISS is a unique way to provide precision long term measurements of primordial high energy charged cosmic rays. AMS was installed on the Station in May 2011. Up to now, 60 billion events have been collected. 40 billion events have been partially analysed. AMS is scheduled to...

A precision measurement by AMS of the positron fraction in primary cosmic rays is presented. The results show that at 275±32 GeV the positron fraction no longer increases with energy. The current status of the anti-proton analysis is also presented.

Precision measurements by AMS on the ISS of the primary cosmic-ray electron flux in the range 0.5 to 700 GeV and the positron flux in the range 0.5 to 500 GeV are presented. The electron flux and the positron flux each require a description beyond a single power-law spectrum. Both the electron flux and the positron flux change their behavior at ∼30 GeV but the fluxes are significantly...

If cosmic ray positrons come from a secondary origin, then their production spectrum is correlated with the production spectrum of other secondary particles such as boron and antiprotons through scattering cross sections measured in the laboratory. This allows to define a first-principle upper bound on the positron flux at the Earth, independent of propagation model assumptions. Using...

We present a measurement of the cosmic ray e+ + e− flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million (e+ + e−) events. The statistics and the resolution of AMS provide a precision measurement of the flux. The flux is smooth and reveals new and distinct information.

A precise measurement of the proton flux in primary cosmic rays with rigidity 1GV to 1.8TV is presented. At rigidities above 50 GV the flux requires a description beyond a single power law.

Just as searches for BSM physics at the LHC necessitate a careful audit of SM backgrounds, the search for signals of dark matter in cosmic rays must contend with production of secondaries like e+ and pbar through cosmic ray propagation in the Galaxy. The theoretical framework for calculating this has however not been directly calibrated at the high energies being explored by AMS-02 and there...

JEM-EUSO on board the International Space Station is a mission that aims at unveiling the nature and the origin of the ultra high energy cosmic rays (UHECRs), and to address basic problems of fundamental physics at extreme energies. The instrument is designed to measure the arrival direction, the energy and, possibly, the nature of these particles. It basically consists of a wide-field of...

TA's recent results on Ultra-High Energy Cosmic Rays (UHECRs) are reported. The energy spectrum based on 20k events above 10^18.2 eV demonstrates a clear dip at 10^18.7 eV and a cutoff at 10^19.7 eV , the shape and the energies of which are well described by the GZK process: energy loss of extra-galactic protons by the interaction with the CMB and IR background. The primary composition...

There has never been a more exciting time in cosmology. But our current paradigm is built upon three pillars that involved unresolved new physics: dark matter, dark energy and inflation. To make cosmology real — and not just an exciting story — we have to resolve the new physics. The dark matter challenge seems especially ripe to solve, perhaps with a triple verification of the particle...
