Pion Exchange Currents in Neutrinoless Double Beta Decay and Limits on Supersymmetry
Amand Faessler, Sergey Kovalenko, Fedor Simkovic +1
We examine the pion exchange mode of neutrinoless double beta decay induced by the R-parity violating quark-lepton operators of the supersymmetric (SUSY) extensions of the standard…
A large Hilbert space QRPA and RQRPA calculation of neutrinoless double beta decay
F. Simkovic, J. Schwieger, G. Pantis +1
A large Hilbert space is used for the calculation of the nuclear matrix elements governing the light neutrino mass mediated mode of neutrinoless double beta decay of Ge76, Mo100, C…
Non-collapsing renormalized QRPA with proton-neutron pairing for neutrinoless double beta decay
F. Simkovic, J. Schwieger, M. Veselsky +2
Using the renormalized quasiparticle random phase approximation (RQRPA), we calculate the light neutrino mass mediated mode of neutrinoless double beta decay of Ge76, Mo100, Te128…
Dominance of Pion-exchange in R-parity Violating Supersymmetry Contributions to Neutrinoless Double Beta Decay
Amand Faessler, Sergey Kovalenko, Fedor Simkovic +1
We present a new contribution of the R-parity violating supersymmetry (SUSY) to neutrinoless double beta decay via the pion exchange between decaying neutrons. The pion coupling to…
The Pauli principle, QRPA and the two-neutrino double beta decay
J. Schwieger, F. Šimkovic, Amand Faessler
We examine the violation of the Pauli exclusion principle in the Quasiparticle Random Phase Approximation (QRPA) calculation of the two-neutrino double beta decay matrix elements,…
