"Zwei Dinge erfüllen das Gemüth mit immer neuer und zunehmender Bewunderung und Ehrfurcht, je öfter und anhaltender sich das Nachdenken damit beschäftigt: der bestirnte Himmel über mir und das moralische Gesetz in mir.
Beide darf ich nicht als in Dunkelheiten verhüllt, oder im Überschwenglichen, außer meinem Gesichtskreise suchen und blos vermuthen; ich sehe sie vor mir und verknüpfe sie unmittelbar mit dem Bewusstsein meiner Existenz."
Immanuel Kant, Kritik der praktischen Vernunft, Beschluß (Riga 1788)

An old story: LFV Z decays

Here you may find some references from the Eighties on flavor-nondiagonal Z-boson decays in the Standard Model (with massive, mixing neutrinos or top quarks in the loop).

Some Fortran programs:


I do not distribute software using this platform. In some cases you may find the programs of interest in the program repository of "Computer Physics Communications". Or you may contact me [or co-authors] directly, you are welcome!


  1. ZFITTER - A Program for the Semi-Analytic Calculation of Predictions for the Process e+e- -> 2f
    click here for the DESY ZFITTER home page.
    The earlier zfitter homepage has been relocated to http://zfitter.education. See: The ZFITTER homepage (25 June 2014), DOI:10.3204/zfitter.education
    Since 2012, there is no institutional ZFITTER support. In case of need, please contact spokesperson@zfitter.education.
    The last released version is ZFITTER v.6.43.
    Numerically, it is identical to ZFITTER v.6.42, distributed via the software deposit of "Computer Physics Communications".
    The actual version is ZFITTER v.6.44beta.
