v2.5: issue with shit output

Asked by Roberto Ruiz

 Hi,

 I'm trying to use version 2.5 for event generation and do the parton shower part
 with pythia8. This in the MSSM context.
The issue I have found is that with the slha file produced by softsusy + shit
the event generation does not work. After some investigation I have found out that
adding by hand the widths of the W and W gauge bosons that are not added by shit to the
slha file it works !
Are you aware of that ?

Thanks !!

Hi,

Yes we are aware of that.
We have indeed decided to be more conservative on invalid input file.
On the other hand to avoid systematic problem, we have added a function to automatically write in the param_card all the entry
which are missing in the param_card.
This function is update missing
(you can call this function when the code propose you to edit the card via the set command and/or by opening the file/...)

Cheers,

Olivier
