CPT invariance examination in quantum electrodynamics bound systems and production of a muonium or antimuonium in the scattering of electrons or positrons on nuclei

摘要

In the present work the possibility of CPT invariance examination of the bound states in quantum electrodynamics (QED) is considered. For this purpose, we calculated the cross section for the processes e~- + Z → Z+M + μ~- and e~+ +Z → Z +M~0 + μ~+. The differential cross section via the invariant mass of (M~0, μ~-) -system and the total cross section of the above processes in the framework of QED are obtained. Also, we considered the registration method of muonium and antimuonium due to the oscillation of basic and exited states on the decay curves. The admixture of the exited muonium to the final state is determined.
