different decays of indistinguishable particles

Hi Roberto,

You can do the following:

p p > go go , go > u u~ n1, go > c c~ n1

Cheers,

Olivier

Hi Olivier,
 Thanks for the input.

So this is the same syntax as for p p > t t~ as given in the syntax examples on the help page, no issues with particles being identical (which was not the case for t t~, of course).

Best,
Roberto

Yes indeed.

Note that
p p > go go , go > u u~ n1
is of course valid (and both go are decayed).

Just to be complete (and for the fun)
p p > go go , go > u u~ n1, go > c c~ n1, go > d d~ n1
is also valid and provides all possible permutations of decays
and
p p > z, z > e+ e-, z > mu+ mu-
will also work having the decay of the Z in both e+ e- and mu+ mu-
Of course in the case of those weird syntax, I would advise to always check that the code works as you expect ;-)

Cheers,

Olivier
