Abstract: AMS is a general purpose particle physics detector on the International Space Station (ISS) to probe the early Universe through the precision measurements of energy spectra of cosmic-ray antiparticles. In its first four years in orbit, AMS has collected more than 60 billion cosmic-ray events up to TeV energies. The AMS collaboration has been presenting the latest results in its quest to understand the origin of cosmic rays and dark matter. These intriguing results were shared and discussed during the gAMS daysh in April/2015. Introduction of AMS and its published results as well as some detailed discussions on the new results will be made in this seminar.
