Fortran run time error

Asked by Asma Hadef

Dear MadGraph team,

I am studying the cuts effect on the higgs signal/ background. I really need your help to overcome some difficulties and find answers to my questions.

1- During the generation of the process p p > j j ta+ ta-, (ta+ > e+ ve vt~, ta- > mu- vmé vt), a message error appears:

The calculation can't be completed and stops in this stage. How can I solve this problem please?

 Besides, how can I speed up the generation time of this process?

2- when no cut is implemented (setting them to 0 in run_card), the calculation is interrupted. I read in the previous problems that this comes from the divergence. Can you gives me more physical details about this problem ? i.e: where is the affected term in the cross section expression that produces this divergence and how the cut solves this problem? Is there any advised reference that well-illustrate the effects of the cuts ?

I appreciate your help and cooperation.

Best,
Asma

Hi,

Please look at Question #236172.

So this looks like either at a gfortran bug -> solution update your gfortran version
or to a too small filesystem for /tmp -> increase the associate partition or change the default gfortran scratch area.

Cheers,

Olivier

> 2- when no cut is implemented (setting them to 0 in run_card), the calculation is interrupted. I read in the previous problems that this comes from the divergence. Can you gives me more physical details about this problem ? i.e: where is the affected term in the cross section expression that produces this divergence and how the cut solves this problem? Is there any advised reference that well-illustrate the effects of the cuts ?

Hi Olivier,

Thank you for your prompt answer.

>Please look at Question #236172.

I didn't find Question #236172 anywhere in Answers and bug reports! Can you please put the direct link into this question please?

Thanks in advance,
Asma
