论文摘要
GBAR实验旨在直接测试地球重力场中超速抗氧的弱对等原理。重力加速$ \ bar {g} $将使用固定高度的反原子的经典自由下落来测量$ 1 \，\％$的精度。通过检测$ \ mathrm {\ bar {h}} $的量子干扰，由于在反射表面上方的量子引力绑定状态而导致的量子干扰来实现$ 10^{ - 6} $的精度。此外，正在并行准备$ \ mathrm {\ bar {h}} $ lamb shift测量测量值，该测量将允许在$ 10 \，\％$的水平上确定抗Proton电荷半径。
The GBAR experiment aims to directly test the Weak Equivalence Principle of ultracold antihydrogen in Earth's gravitational field. The gravitational acceleration $\bar{g}$ will be measured to a precision of $1\,\%$ using a classical free fall of the anti-atoms from a fixed height. Reaching a precision of $10^{-6}$ is planned by performing a "quantum free fall" experiment by detecting quantum interference of $\mathrm{\bar{H}}$ due to quantum gravitational bound states above a reflecting surface. Additionally, a $\mathrm{\bar{H}}$ Lamb shift measurement is being prepared in parallel that will allow to determine the antiproton charge radius at the level of $10\,\%$.
