Description

This article describes a study that was conducted to determine what would happen if a magnetobound positronium system encountered a finite-mass antiproton. The simulation incorporates a strong magnetic field (1 T) similar to that found within Penning traps. The simulation shows that with a finite-mass antiproton, the electron will be ejected from the system, and the positron is captured into a bound state with an antiproton thereby synthesizing antihydrogen.

Notes

Abstract: Through classical trajectory simulation, it is found that antihydrogen can be synthesized via three body recombination involving magnetobound positronium. It has previously been reported that giant cross-magnetic-field steps can occur as a result of electron-positron pair collisions. An electron-positron pair collision can result in a correlated drift of the particles perpendicular to a constant strong magnetic field. While the two particles remain in their correlated drift, they are referred to as a magnetobound positronium system. Thus, magnetobound positronium is a twobody system consisting of a positron-electron pair that becomes temporarily bound together in
the presence of a magnetic field. This study was conducted to determine what would happen if a magnetobound positronium system encountered a finite-mass antiproton. The simulation incorporates a strong magnetic field (1 T) similar to that found within Penning traps. The simulation shows that with a finite-mass antiproton, the electron will be ejected from the system, and the positron is captured into a bound state with an antiproton thereby synthesizing antihydrogen.
