  • First Transport of Antiprotons in Our Open Penning Trap System BASE-STEP

    First Transport of Antiprotons in Our Open Penning Trap System BASE-STEP The fractional resolution achieved in our precision tests of matter–antimatter symmetry – comparing the fundamental properties of antiprotons and protons – is improving rapidly. The most precise test of CPT invariance in the baryon sector, done in our trap system, has reached a fractional…

  • Research Prizes for BASE Members 2

    Research Prizes for BASE Members Two BASE members have recently received international awards for their contributions to our experiments. At BASE, we develop and operate advanced Penning-trap systems to study the properties of single antiprotons with world-leading precision. Our goal is to compare matter and antimatter at the most fundamental level and to test the symmetries…

  • Top-10 Physics Breakthrough of 2025

    Top-10 Physics Breakthrough of 2025 We are thrilled and deeply honored that our work on the first non-destructive coherent spectroscopy of a single antiproton spin has been selected as one of the Top 10 Breakthroughs of the Year by Physics World. This recognition highlights a major step forward in precision antimatter physics, achieved through the…
