Abstract The Antiproton Decelerator (AD) facility of CERN began operation in 1999 to serve
experiments for studies of CPT invariance by precision laser and microwave spectroscopy of …

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 …

The antihydrogen formation by charge exchange between cold antiprotons and Rydberg
positronium P s* is studied by using the classical trajectory Monte Carlo method. In the …

The main goal of the AEgIS experiment at CERN is to test the weak equivalence principle for
antimatter. AEgIS will measure the free-fall of an antihydrogen beam traversing a …

The AEgIS experiment is presently almost completely installed at CERN. It is currently taking
data with antiprotons, electrons and positrons. The apparatus is designed to form a cold …

We compare classical and quantum predictions of the cross section for anti-hydrogen
formation by charge exchange between Rydberg positronium and antiprotons as a function …

experiment's main goal is to measure the local gravitational acceleration of antihydrogen
and thus perform a direct test of the weak equivalence principle with antimatter. In the first …

Measurements of the positronium (Ps) energy and formation fraction in reflection and
transmission from a thin meso-structured silica target have been conducted using single …

The AEgIS Experiment is an international collaboration based at CERN whose aim is to
perform the first direct measurement of the gravitational acceleration g of antihydrogen in the …

The goal of the AE bar g IS experiment at the Antiproton Decelerator (AD) at CERN, is to
measure directly the Earth's gravitational acceleration on antimatter by measuring the free …
