A theoretical underpinning of the standard model of fundamental particles and interactions is CPT invariance, which requires that the laws of physics be invariant under the combined discrete operations of charge conjugation, parity and time reversal. Antimatter, the existence of which was predicted by Dirac, can be used to test the CPT theorem—experimental investigations involving comparisons of particles with antiparticles are numerous. Cold atoms and anti-atoms, such as hydrogen and… Expand
Trapped antihydrogen: A new frontier in fundamental physics
Antihydrogen, the bound state of an antiproton and a positron, has been produced at low energies at CERN since 2002. Antihydrogen is of interest for use in precision tests of nature's fundamentalExpand
Trapped antihydrogen
TLDR
T trapping of antihydrogen atoms is demonstrated and opens the door to precision measurements on anti-atoms, which can soon be subjected to the same techniques as developed for hydrogen. Expand
Fundamental Physics with Antihydrogen
Antihydrogen—the antimatter equivalent of the hydrogen atom—is of fundamental interest as a test bed for universal symmetries—such as CPT and the Weak Equivalence Principle for gravitation.Expand
Physics with antihydrogen
Performing measurements of the properties of antihydrogen, the bound state of an antiproton and a positron, and comparing the results with those for ordinary hydrogen, has long been seen as a routeExpand
Antimatter transport processes
A comparison of the 1S-2S transitions of hydrogen and antihydrogen will yield a stringent test of CPT conservation. Necessarily, the antihydrogen atoms need to be trapped to perform high precisionExpand

Observation of Cold Antihydrogen
The simplest electrical neutral system made entirely of antimatter is the antihydrogen atom ( H ¯ 0 ) consisting of a positron (e+) orbiting an antiproton ( p ¯ ). The first H ¯ 0 atoms produced in pExpand
An experimental limit on the charge of antihydrogen
TLDR
A retrospective analysis of the influence of electric fields on antiHydrogen atoms released from the ALPHA trap finds a mean axial deflection, which leads to a bound on the charge Qe of antihydrogen of Q=(−1.3±1.1±0.4) × 10−8.4, where e is the unit charge. Expand
Pulsed production of antihydrogen
Antihydrogen atoms with K or sub-K temperature are a powerful tool to precisely probe the validity of fundamental physics laws and the design of highly sensitive experiments needs antihydrogen withExpand
