<title>Precision calculations to the fine shift of S levels in the muonium atom</title>

Abstract As part of the well-known task about a motion of charged particle in central forces field, a certain parallelism for electronic distribution between the atomic and subatomic ''orbits'' can be established.In this conjuncture the ground state of muonium atom as in transition electron-nuclear structure is highlighted. Moreover, there is specifically nuclear solution of fine-structure constant which with a hyper-fine structure, like of the Lamb shift of hydrogen atom, is unambiguously associated.Such a special approach, in the terms of electric interaction, may serve as an extension to the existing meson-boson classification.In particular, some idea about a versatility of the Higgs mechanism in nuclear reactions put forward for consideration here.But it would be just spatial abstraction, where subatomic matter expands as into infinity. And what would be beyond the edge of the universe?

Lepton Number Violating

The MACS experiment performed at PSI in the 1990s provided an yet unchallenged upper bound on the probability for a spontaneous conversion of the muonium atom, { M=}({\mu^+e^-})M=(μ+e−), into its antiatom, antimuonium {\overline{{M}} = }({\mu^-e^+})M¯=(μ−e+). It comprises the culmination of a series of measurements at various accelerator laboratories worldwide. The experimental limits on the process have provided input and steering for the further development of a variety of theoretical models beyond the standard theory, in particular for models which address lepton number violating processes and matter-antimatter oscillations. Several models beyond the standard theory could be strongly disfavored. There is interest in a new measurement and improved sensitivity could be reached by exploiting the time evolution of the conversion process, e.g., at intense pulsed muonium sources.
