Hello,

Is there some way to calculate globally the partial decay with for the
Z0 particle to four particles of one generation (say e,n,u,d or
tau,n,s,c)? The coefficient one gets when trying to sum the decays to
each specific particle is rather strange.

I have elaborated a little bit the question; which is strange is that
the dependence on the sin weinberg gets a minimum for the value at GUT
scale (which it turn depends on the charge content of the theory,
remember).

There are other related consequences, you can see a two page PDF here,

but I still keep wondering by the posibility of considering the full
decay in a single stroke. Any ideas or comments?

Yours,

Alejandro
