反质子电荷半径

The anti-proton charge radius

P. Crivelli, D. Cooke, M. W. Heiss

摘要:

欧洲核子研究中心的超低能量反质子(ELENA)环即将投入使用,反质子减速器(AD)的升级,以及AD大厅中预期通量为$10^{8}$ e $^+$ /s的强慢正电子束的安装,将为反氢($\bar{\text{H}}$)的新实验开辟可能性。本文提出了一种测量$\bar{\text{H}}$兰姆位移的方法。对于一个月的数据采集,我们预计不确定性为100 ppm。这将提供CPT的测试和反质子电荷半径在10%水平的第一次测定。

英文摘要:

The upcoming operation of the Extra Low ENergy Antiprotons (ELENA) ring at CERN, the upgrade of the anti-proton decelerator (AD), and the installation in the AD hall of an intense slow positron beam with an expected flux of $10^{8}$ e$^+$/s will open the possibility for new experiments with anti-hydrogen ($\bar{\text{H}}$). Here we propose a scheme to measure the Lamb shift of $\bar{\text{H}}$. For a month of data taking, we anticipate an uncertainty of 100 ppm. This will provide a test of CPT and the first determination of the anti-proton charge radius at the level of 10%.
