Zusammenfassung:
We present the possible mixing effects associated with the low-energy limit
of a Standard-Model extension by two abelian gauge groups U(1)_1 x U(1)_2. We
derive general formulae and approximate expressions that connect the gauge
eigenstates to the mass eigenstates. Applications using the well-studied groups
U(1)_B, U(1)_(B-L), U(1)_(L_alpha - L_beta) (L_alpha being lepton flavor
numbers), and U(1)_DM (a symmetry acting only on the dark matter sector) are
discussed briefly.
