Bound-state decay of a charged scalar particle in an external Coulomb field
Andrzej Czarnecki, Artem O. Davydov
We determine the decay rate of a scalar particle bound to a light nucleus, numerically and analytically. As a model system, we consider a negatively charged kaon in the ground…
Radiative Corrections in Bound States: Recent Results
Andrzej Czarnecki, Artem O. Davydov
Two recent studies of radiative corrections to bound state properties are discussed. The change of the decay rate of a muon bound to a light nucleus has been calculated for several…
Total decay rate of a muon bound to a light nucleus
Andrzej Czarnecki, A. O. Davydov, M. Y. Kaygorodov
We revisit the total decay rate of a muon being in the ground state of a Coulomb potential with atomic charge numbers . The discrepancy between the perturbative $(α…
Study of atomic effects on electron spectrum in bound-muon decay process
M. Y. Kaygorodov, Y. S. Kozhedub, A. V. Malyshev +3
For the bound-muon decay process, the study of atomic effects on the electron spectrum near its endpoint is performed within the framework of the Fermi effective theory. The analys…
