Antiproton Magnetic Moment
Antiproton Magnetic Moment Today we report in Nature on an improved measurement of the magnetic moment of the antiproton. The new measurement outperforms our old record measurement by a factor of 350 in experimental precision. Our updated value gpbar/2=2.792 847 3441 (42) is consistent with the magnetic moment of the proton gp=2.792 847 350 (9),

WELCOME
WELCOME BASE is a multinational collaboration at the Antiproton Decelerator (AD) of CERN which aims at precise comparisons of the fundamental properties of antiprotons and protons. Such comparisons provide stringent tests of charge-parity-time reversal invariance which is the most fundamental symmetry in the Standard Model of particle physics. The BASE collaboration observed the first spin

Research Prizes for BASE Members
Research Prizes for BASE Members BASE members Takashi Higuchi and Andreas Mooser received research prizes for their work in BASE. Takashi Higuchi was awarded a poster prize at the LEAP2016 conference in Kanazawa, Japan, which was sponsored by Nature Physics. For his PhD thesis, in which he performed the first direct high-precision measurement of the

Direct measurement of the free cyclotron frequency with a single trapped particle
Direct measurement of the free cyclotron frequency with a single trapped particle Penning traps are extremely powerful and versatile tools for high precision physics. This enormous impact is mainly based on the fact that in the magnetic field B of the trap the free cyclotron frequency of a trapped particle can be measured with high

Observation of Spin Flips with a Single Trapped Proton
Observation of Spin Flips with a Single Trapped Proton We have observed spin quantum-jumps with a single trapped proton for the first time. This is a pioneering step forward in the endeavor to directly measure the magnetic properties of the proton with high precision. The measuring principle is based on the observation of a single
