Welcome to the Max-Planck-Institut für Kernphysik (MPIK, Max Planck Institute for Nuclear Physics) in Heidelberg, one of 83 institutes and research establishments of the  Max-Planck-Gesellschaft (Max Planck Society). The MPIK does experimental and theoretical basic research in the fields of Astroparticle Physics (crossroads of particle physics and astrophysics) and Quantum Dynamics (many-body dynamics of atoms and molecules).

The BASE experiment at CERN compares protons and antiprotons with high precision

The Baryon Antibaryon Symmetry Experiment (BASE) at CERN's Antiproton Decelerator (AD) reports the most precise comparison of the charge-to-mass ratio of the proton to its antimatter equivalent, the antiproton. The charge-to-mass ratio — an important property of particles — can be measured by observing the oscillation of a particle in a magnetic field. The new result shows no difference between the proton and the antiproton, with a four-fold improvement in the energy resolution compared with previous measurements [Nature, 12 August 2015].
