Our current understanding of the Universe comes, among others, from particle physics and cosmology. In particle physics an almost perfect symmetry between matter and antimatter exists. On cosmological scales, however, a striking matter/antimatter imbalance is observed. This contradiction inspires comparisons of the fundamental properties of particles and antiparticles with high precision. Here we report on a measurement of the g-factor of the antiproton with a fractional precision of 0.8 parts…

A parts-per-billion measurement of the antiproton magnetic moment
TLDR
A high-precision measurement of the magnetic moment of the antiproton in units of the nuclear magneton μN with a fractional precision of 1.5 parts per billion is reported, which constrains the magnitude of certain CPT-violating effects to below 1.8 × 10−24 gigaelectronvolts.
Challenging the standard model by high-precision comparisons of the fundamental properties of protons and antiprotons
TLDR
The BASE collaboration investigates the fundamental properties of protons and antiprotons, such as charge-to-mass ratios and magnetic moments, using advanced cryogenic Penning trap systems, and sets the most stringent constraint on directly measured antiproton lifetime.
Direct limits on the interaction of antiprotons with axion-like dark matter
TLDR
Spin-flip resonance data are used to place direct constraints on the interaction of ultralight axion-like particles with antiprotons, improving the sensitivity to the corresponding coupling coefficient by five orders of magnitude.
350-fold improved measurement of the antiproton magnetic moment using a multi-trap method
We summarize our recent 1.5 parts per billion measurement of the antiproton magnetic moment using the multi Penning-trap system of the BASE collaboration. The result was achieved by combining the
Observation of the 1S–2S transition in trapped antihydrogen
TLDR
The observation of the 1S–2S transition in magnetically trapped atoms of antihydrogen is reported, it is determined that the frequency of the transition, which is driven by two photons from a laser at 243 nanometres, is consistent with that expected for hydrogen in the same environment.
Quantum logic inspired techniques for spacetime-symmetry tests with (anti-)protons
Cosmological observations as well as theoretical approaches to physics beyond the standard model provide strong motivations for experimental tests of fundamental symmetries, such as CPT invariance.
In-beam measurement of the hydrogen hyperfine splitting and prospects for antihydrogen spectroscopy
TLDR
A measurement of the zero-field hydrogen GS-HFS is presented using the spectroscopy apparatus of ASACUSA's antihydrogen experiment and proves the most precise determination of this quantity in a beam and verifies the developed spectroscopic methods for the antihydrogens HFS experiment to the p.p.b. level.
Double-trap measurement of the proton magnetic moment at 0.3 parts per billion precision
TLDR
A direct high-precision measurement of the magnetic moment μp of the proton in units of the nuclear magneton μN is reported, which improves the previous best measurement by a factor of 11, and is consistent with the currently accepted value.

The field of cold antimatter physics has rapidly developed in the last 20 years, overlapping with the period of the Antiproton Decelerator (AD) at CERN. The central subjects are CPT symmetry tests
Antihydrogen accumulation for fundamental symmetry tests
TLDR
An efficient and high-precision method for trapping and stacking antihydrogen by using controlled plasma is demonstrated, with a record of 54 detected annihilation events from a single release of the trapped anti-atoms accumulated from five consecutive cycles.

The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing the magnetic moments of the proton and
High-precision comparison of the antiproton-to-proton charge-to-mass ratio
TLDR
The result can be interpreted as a stringent test of the weak equivalence principle of general relativity using baryonic antimatter, and it sets a new limit on the gravitational anomaly parameter of < 8.7 × 10−7.
An improved limit on the charge of antihydrogen from stochastic acceleration
TLDR
By applying stochastic acceleration to trapped antihydrogen atoms, an experimental bound is determined on theAntihydrogen charge, Qe, of |Q| < 0.71 parts per billion (one standard deviation), in which e is the elementary charge.
Muon (g- 2): experiment and theory.
TLDR
Because both the theoretical and experimental values of the muon anomaly are determined to high precision, it is an excellent place to search for the effects of new physics or to constrain speculative extensions to the Standard Model.

A review of the experimental and theoretical determinations of the anomalous magnetic moment of the muon is given. The anomaly is defined by a=(g-2)/2, where the Land\'e g-factor is the
Two-photon laser spectroscopy of antiprotonic helium and the antiproton-to-electron mass ratio
TLDR
Two-photon spectroscopy of antiprotonic helium, in which 3He+ and 4He+ isotopes are irradiated by two counter-propagating laser beams, is reported, which derived an antiprodynamics mass ratio that agrees with the proton-to-electron value known to a similar precision.
Direct high-precision measurement of the magnetic moment of the proton
TLDR
The direct high-precision measurement of the magnetic moment of a single proton using the double Penning-trap technique is reported, which improves the precision of the forty-year-old indirect measurement and can be improved by a factor of at least 1,000.
One-particle measurement of the antiproton magnetic moment.
TLDR
For the first time a single trapped antiproton (p) is used to measure the p magnetic moment μ(p), consistent with the prediction of the CPT theorem.
Origin of the matter-antimatter asymmetry
Although the origin of matter-antimatter asymmetry remains unknown, continuing advances in theory and improved experimental limits have ruled out some scenarios for baryogenesis, for example,
CPT tests in the neutral kaon system.
