A Bayesian Data Analysis Method for an Experiment to Measure the Gravitational Acceleration of Antihydrogen †
Abstract
:1. Introduction
- There is an experimentally limited amount of trapped antihydrogen.
- The efficiency of detection in the up and down regions may be asymmetric.
- Some small fraction of antihydrogen escaping downwards may be detected in the up region (and vice versa).
- The precise number of total trapped anti-atoms is unknown experimentally.
- Cosmic rays passing through the apparatus lead to a background annihilation rate, which may be up–down asymmetric.
2. Materials and Methods
2.1. Determining the Experimental Escape Curve
2.2. Determining the Antihydrogen Gravitational Acceleration
3. Discussion
