Assuming hydrogen is charge neutral, CPT invariance demands that antihydrogen also be charge neutral. Quantum anomaly cancellation also demands that antihydrogen be charge neutral. Standard techniques based on measurements of macroscopic quantities of atoms cannot be used to measure the charge of antihydrogen. In this paper, we describe how the application of randomly oscillating electric fields to a sample of trapped antihydrogen atoms, a form of stochastic acceleration, can be used to place…

An improved limit on the charge of antihydrogen from stochastic acceleration

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.

Observation of the 1S–2S transition in trapped antihydrogen

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.

An experimental limit on the charge of antihydrogen

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.
