Abstract The AEgIS experiment aims at producing antihydrogen (and eventually measuring the effects of the Earth gravitational field on it) with a method based on the charge exchange reaction between antiproton and Rydberg positronium. To be precise, This article is part of the Topical Collection on Proceedings of the 13th International Conference on Low Energy Antiproton Physics (LEAP 2018) Paris, France, 12-16 March 2018 Edited by Paul Indelicato, Dirk van der Werf and Yves Sacquin Nicola Zurlo

antiprotons are delivered by the CERN Antiproton Decelerator (AD) and are trapped in a multi-ring Penning trap, while positronium is produced by a nanoporous silica target and is excited to Rydberg states by means of a two steps laser excitation. New Monte Carlo simulations are presented in this paper in order to investigate the current status of the AEgIS experiment [1] and to interpret the recently collected data [2].

1 Introduction Since the first synthesis of cold antihydrogen [3], several experiments in the same field [4–6] have exploited (and substantially improved) the same technique, based on the mixing of positrons and antiprotons clouds interacting via three body recombination, with only one relevant exception [7]. In this work, the feasibility of a different way to
