Neutrino mediated muon--electron conversion in nuclei revisited
F. Simkovic, V. E. Lyubovitskij, Th. Gutsche +2
The non-photonic neutrino exchange mechanism of the lepton flavor violating muon-electron conversion in nuclei is revisited. First we determine the nucleon coupling constants for t…
Distinguishing the neutrinoless double beta decay mechanisms
Fedor Simkovic, Amand Faessler
Many new neutrinoless double beta decay (0nbb) experiments are planned or in preparation. If the 0nbb-decay will be detected, the key issue will be what is the dominant mechanism o…
The (muon^-,muon^+) conversion in nuclei as a probe of new physics
Fedor Simkovic, Amand Faessler, Sergey Kovalenko +1
A detailed study of the muonic analogue of neutrinoless double beta decay, (muon^-,muon^+) conversion, has been carried out for the A=44 nuclear system. We studied several lepton n…
Neutrinoless Double Beta Decay of Ge76, Se82, Mo100 and Xe136 to excited 0^+ states
F. Simkovic, M. Nowak, W. A. Kaminski +2
The neutrinoless double beta decay transition to the first excited 0^+ collective final state is examined for A=76, 82, 100 and 136 nuclei by assuming light and heavy Majorana neut…
New results for two-neutrino double beta decay with large particle-particle two body proton-neutron interaction
A. A. Raduta, O. Haug, F. Simkovic +1
A model many-body Hamiltonian describing an heterogenous system of paired protons and paired neutrons and interacting among themselves through monopole particle-hole and monopole p…
The muon-positron conversion in nuclei mediated by light Majorana neutrinos
Fedor Simkovic, Pavol Domin, Sergey Kovalenko +1
We study the lepton number violating muon-positron conversion in nuclei mediated by the exchange of virtual light Majorana neutrinos. We found that a previously overlooked imaginar…
