简单原子精确光谱对反物质反引力的限制
A constraint on antigravity of antimatter from precision spectroscopy of simple atoms
摘要：
考虑反粒子的反引力是各种实验项目的一个有吸引力的目标。有一些理论上的论点反对它，但它不是很清楚什么样的实验数据和理论建议所涉及的。在本文中，我们提出了一些简单的理论建议和一些实验数据的基础上，对反重力的可能性直截了当的论点。数据如下：关于太阳系相对于银河系中心旋转的天体物理数据以及关于氢和正电子素的精确光谱数据。对无引力场情况的理论建议是：电子和正电子质量相等，质子和正电子电荷相等。我们还假设，QED是正确的，在准确性的水平，它是明确证实实验。
英文摘要：
Consideration of antigravity for antiparticles is an attractive target for various experimental projects. There are a number of theoretical arguments against it but it is not quite clear what kind of experimental data and theoretical suggestions are involved. In this paper we present straightforward arguments against a possibility of antigravity based on a few simple theoretical suggestions and some experimental data. The data are: astrophysical data on rotation of the Solar System in respect to the center of our galaxy and precision spectroscopy data on hydrogen and positronium. The theoretical suggestions for the case of absence of the gravitational field are: equality of electron and positron mass and equality of proton and positron charge. We also assume that QED is correct at the level of accuracy where it is clearly confirmed experimentally.
