Re: GEANT Branching Fraction Table

[Matthew Shepherd <mashephe@indiana.edu>]

Sascha,

Thanks -- yes, for PYTHIA, just the eta itself is passed onto GEANT.   
Do you know how to override the default decay branching fractions in  
the code?

I see that (unfortunately) GEANT has builtin a non-zero branching  
fraction for eta -> pi^0 gamma gamma which one of the rare signal  
mdoes that Liping is interested in.
