Facing problem

Asked by Sarif Khan

I was generating a process in Madg5 and I faced the following problem,

Command "generate_events -f" interrupted in sub-command:
"set max_npoint_for_channel 0" with error:
KeyError : 33
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.

Can you please help me in this regard?

Hi,

Like this I have no idea what the problem can be. Can you copy/paste the debug file such that I would have an idea of what you are trying to do.

Cheers,

Olivier

Here I am giving the details, I am getting a warning but I can not overcome it by the procedure it is showing. Can you please help me in avoiding the warning? If I remove the ~rh0 > ~n0 j j part then I am not getting the warning.

generate p p > ~rhp+ ~rh0, (~rhp+ > ~n0 j j,~rh0 > ~n0 j j)

Decay information for particle(s) ~rh0 is discarded.
Please check your process definition carefully.
This warning usually means that you forgot parentheses in presence of subdecay.

Hi,

You either need to do
> generate p p > ~rhp+ ~rh0, (~rhp+ > ~n0 j j) , (~rh0 > ~n0 j j)
 or
> generate p p > ~rhp+ ~rh0, ~rhp+ > ~n0 j j,~rh0 > ~n0 j j

With your definition of your parenthesis, you specify that the ~rh0 decay should be a sub decay of ~rhp+ decay.
Which does not make sense obviously

Cheers,

Olivier
