ROOT and PYTHIA 8 (for neutron decay)

ROOT
1

Hi all,
I need to decay the neutrons contained in my root file. The “old” pythia 6 has no neutron decay defined, so I guess the methods of TPythia class are probably useless. Since the new pythia 8 has neutron decay I’d like to ask :"Is there a way to use pythia 8 in ROOT?"
Or have I to grab the code from pythia c++ source and put it into my routine? (ugly but maybe working)
Thanks
Roberto

Could you point me to more information on the Pythia8 interface. I cannot seem to find any information on this. Is the Pythia8 interface available?

Thanks and best regards,
Florian

Yes the Pythia8 interface is available (since version 5.18) See
root.cern.ch/root/html/TPythia8.html
and $ROOTSYS/tutorials/pythia/pythia8.C
