The project is an international cooperation project designed to provide atheoretical support of experimental activity, performed or planned at LMU, MPQ, CERN and PSI in Switzerland, by Russian theoreticians. The experiments will deliver high-resolution spectroscopic results on simple atoms, such as ordinary and muonic hydrogen and many others.Recently, a certain discrepancy in results for the proton charge radius, obtained from spectroscopy muonic and ordinary hydrogen, was discovered. The work within the project is focused on precision theory of energy levels of low-lying states in muonic hydrogen and deuterium. Its purpose is a systematic development of theory of muonic hydrogen in order to verify previous calculations and find new higher-order corrections.It is expected that certain theoretical methods will also be generalized for application in light and medium-Z muonic atoms, as well as to other atoms, such as, e.g., positronium and muonium.Because of the existing controversy a reexamination of existing world data on the subject will be also performed.

该项目是一个国际合作项目，旨在为俄罗斯理论家在瑞士LMU、MPQ、CERN和PSI进行或计划的实验活动提供理论支持。这些实验将提供简单原子的高分辨率光谱结果，如普通和μ子氢和许多其他原子。最近，发现质子电荷半径的结果存在一定的差异，从光谱μ子和普通氢得到。该项目的工作重点是μ介子氢和氘的低能态能级的精确理论。它的目的是系统地发展μ子氢的理论，以验证以前的计算和找到新的高阶修正。预计某些理论方法也将推广应用于轻和中等Z μ子原子，以及其他原子，例如，正电子素和μ素。由于目前存在的争议，也将重新审查有关这一主题的现有世界数据。
