μ介子氢和π介子原点波函数的二阶修正

Second-order corrections to the wave function at origin in muonic hydrogen and pionium

Vladimir G. Ivanov, Evgeny Yu. Korzinin, Savely G. Karshenboim

摘要:

考虑了μ子原子和奇异原子中原点处波函数的非相对论二阶修正。修正是由于电子真空极化。由于各种有效的方法,考虑到量子电动力学和强子效应,这样的修正是有趣的。原点处的波函数在计算介子寿命、各种有限核尺寸效应和超精细分裂中起着关键作用。得到的结果为$1s$和$2s$状态的π介子和μ介子氢和氘和π 鎓,一个绑定系统的$π^+$和$π^-$。应用的超精细结构和Lamb位移μ介子氢也被认为是。

英文摘要:

Non-relativisitic second-order corrections to the wave function at origin in muonic and exotic atoms are considered. The corrections are due to the electronic vacuum polarization. Such corrections are of interest due to various effective approaches, which take into account QED and hadronic effects. The wave function at origin plays a key role in the calculation of the pionium lifetime, various finite nuclear size effects and the hyperfine splitting. The results are obtained for the $1s$ and $2s$ states in pionic and muonic hydrogen and deuterium and in pionium, a bound system of $π^+$ and $π^-$. Applications to the hyperfine structure and the Lamb shift in muonic hydrogen are also considered.
