Madspin_interupted_with_error

Hi,

Am I correct that you try to use MadSpin for a 1>2 core process?
Not sure that such process is handle so far.

Cheers,

Olivier

Dear Olivier,
      I was trying to find the decay width of Z > all possible decay mode, which I chose to be 1>2 process only... Can you suggest some materials to understand MadSpin card and its output to be understood...

Thanks,

Subhasish

Hi,

> Can you suggest some materials to understand MadSpin card and its output to be understood...

- The official paper for MadSpin is: arXiv:1212.3460
detailed/updated information about the card option are presented here: https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/MadSpin

> I was trying to find the decay width of Z > all possible decay mode, which I chose to be 1>2 process only…

Then you are probably more interested by MadWidth: arXiv:1402.1178
This is a code which automate the width computation. In that paper, you have the description of the various options of the code to allow,
3/4 body decay.

Cheers,

Olivier
