Exact relativistic tritium beta-decay endpoint spectrum in a hadron model
Fedor Simkovic, Rastislav Dvornicky, Amand Faessler
We present the relativistic calculation of the beta-decay of tritium in a hadron model. The elementary particle treatment of the transition 3H -> 3He + e^- + nu_e is performed in a…
Chiral corrections to the vector and axial couplings of quarks and baryons
Amand Faessler, Thomas Gutsche, Barry R. Holstein +1
We calculate chiral corrections to the semileptonic vector and axial quark coupling constants using a manifestly Lorentz covariant chiral quark approach up to order O(p4) in the tw…
Dependence of nucleon properties on pseudoscalar meson masses
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We discuss the sensitivity of nucleon properties (mass, magnetic moments and electromagnetic form factors) on the variation of the pseudoscalar meson masses in the context of the p…
Gamow-Teller strength distributions for double-beta-decaying nuclei within continuum-QRPA
S. Yu. Igashov, V. A. Rodin, M. H. Urin +1
A version of the pn-continuum-QRPA is outlined and applied to describe the Gamow-Teller strength distributions for -decaying open-shell nuclei. The calculation results obtained…
Overconstrained estimates of neutrinoless double beta decay within the QRPA
Amand Faessler, Gianluigi Fogli, Eligio Lisi +3
Estimates of nuclear matrix elements for neutrinoless double beta decay (0nu2beta) based on the quasiparticle random phase approximations (QRPA) are affected by theoretical uncerta…
Nuclear and particle physics aspects of the 2nbb-decay of 150Nd
Rastislav Dvornicky, Fedor Simkovic, Amand Faessler
A discussion is given on possible realization of the Single State Dominance (SSD) hypothesis in the case of the two-neutrino double beta decay(2nbb-decay) of 150Nd with 1^- ground…
