28. Juni 2016 Institut für Kernphysik (IKP) Folie 8 Physics Case – The Fate of Antimatter Why does the Universe contain matter at all and not light only ?

28. Juni 2016 Institut für Kernphysik (IKP) Folie 9 Physics Case – The Fate of Antimatter Since there is matter – is there also (relic) antimatter somewhere?

28. Juni 2016 Institut für Kernphysik (IKP) Folie 10 AMS – Alpha Magnetic Spectrometer Search for (relic) antimatter!

28. Juni 2016 Institut für Kernphysik (IKP) Folie 11 AMS – A Local Asymmetry? AMS-02: first result – „positron fraction“
