用经典的轨迹模拟研究了反质子束通过电子-正电子等离子体产生磁结合正电子的反氢束的形成。通过模拟，发现磁结合正电子可以通过三体重组合成反氢。此前有报道称，带电物质粒子和反物质粒子之间的二元碰撞可能导致巨大的跨磁场粒子漂移。电子-正电子对碰撞会导致两个粒子垂直于磁场的相关漂移。当两个粒子保持相关漂移时，它们被称为磁结合正电子。这项研究是为了确定如果磁结合正电子系统遇到反质子会发生什么。模拟结果表明，正电子可以被捕获到与反质子的束缚态。本研究还考虑了电子-正电子碰撞俯仰角对磁结合正电子产生反氢的影响。
The formation of an antihydrogen beam by transporting an antiproton beam through an electron-positron plasma that produces magnetobound positronium is studied using a classical trajectory simulation. Through 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 particle drifts can occur as a result of binary collisions between charged matter particles and their antimatter counterparts. An electron-positron pair collision can result in a correlated drift of the two particles, perpendicular to a magnetic field. While the two particles remain in their correlated drift, they are referred to as magnetobound positronium. This study was conducted to determine what would happen if a magnetobound positronium system encountered an antiproton. The simulation shows that a positron can be captured into a bound state with an antiproton. This study also considers the effect that the electron-positron collision pitch angle has on antihydrogen production via magnetobound positronium.
