Problem with hgg_plugin

Hi,

This is clearly a bug.
I have succesfully reproduce it and locate the function responsible for such bad behaviour (I think).
But I need more time to find the correct patch (that part of the code is very complex) and to test it.

Cheers,

Olivier

Hi Olivier,

Thank you for checking.
Do you think I can use the heft model instead?

Best,
Amin

Hi again,

I found a similar issue in another process, even though the error is different. I am generating p p > leptons + jets and with gridpack I get:

P2_gq_llgq,P2_gg_vltapqq,P2_qq_vltapqq SubProcesses doesn't have available phase-space.
            Please check mass spectrum.

then the error:

Error when reading /home/abouibrahim.a/MG5_aMC_v2_6_0/bin/LL/SubProcesses/P2_gg_llqq/G1/results.dat
Command "generate_events -f" interrupted with error:

More information is found in '/home/abouibrahim.a/MG5_aMC_v2_6_0/bin/LL/run_01_tag_1_debug.log'.
Please attach this file to your report.

Is that the same problem as before? I can send you the log file if needed.

Thank you again,
Amin

Hi,

I would actually advise you to use the heft model. But the problem here is not in the model definition.
So both leads to this crash.

For the second problem, if you can give me the details, I will check after having fix this one.

Cheers,

Olivier

Hi,

The faulty change in the code seems to be this one:
https://bazaar.launchpad.net/~mg5core1/mg5amcnlo/2.6.2/revision/258.1.62

Reverting it seems to solve the issue (I did not make a full run, just run the previously faulty channel)

But reverting such patch is likely to be a bad solution since it was done for a reason. I still have to investigate but if you are in a rush, try it and if it goes through then you should be fine.

Cheers,

Olivier

Hi Olivier,

What do you mean by reverting the patch? You mean undoing the change in code? How can I do that?

For the other crash, here are the details:

define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
define lept = l+ l- vl vl~
generate p p > lept lept $ X V h QED=2 @0
add process p p > lept lept j $ X V h QED=2 @1
add process p p > lept lept j j $ X V h QED=2 @2

Thank you again.

Best,
Amin

you can use patch -R

(or just apply the patch without the option -R and most patch will propose to you to run it with -R)

thanks for the process, is this also in heft? or in sm?

Cheers,

Olivier

PS: I have run so far tt~/Z/w+/h up to three jets and they all work fine.

I got you.
Yes, this is also sm-no_b_mass.

Thank you,
Amin

I forgot to mention that I am using version 2.6.0. Does reverting this patch work on 2.6.0?

Best,
Amin

should be yes.

Olivier

Hi Olivier,

After reversing the patch, the first issue was solved, i.e. gluon fusion using hgg_plugin has completed with out errors.
Now the second problem (lepton production) still persists. I am getting this warning and error:

P2_gq_tamtapgq,P2_gq_vltapgq,P0_qq_tamtap SubProcesses doesn't have available phase-space.
            Please check mass spectrum.

Error when reading /home/abouibrahim.a/MG5_aMC_v2_6_0/bin/LL/SubProcesses/P2_gg_llqq/G1/results.dat
Command "generate_events -f" interrupted with error:
ValueError : need more than 5 values to unpack

More information is found in '/home/abouibrahim.a/MG5_aMC_v2_6_0/bin/LL/run_01_tag_1_debug.log'.
Please attach this file to your report.

What could be the problem here?

Thank you,
Amin

Hi Amin,

I still have to convince myself that such change is the correct one to do. When I will be convinced (or find a change that will convince me) then I will move on your second problem.

Cheers,

Olivier

Hi,

Just to point that indeed this is not good enough since it fails
for qq~>aagqq~ in the heft
(actually both .and. and .or. fails).

Cheers,

Olivier

Thanks Olivier.
I will wait for a resolution to this issue.

Best,
Amin

Hi Olivier,

I applied the patches and everything is working now.
Thank you very much.

Best,
Amin

Thanks Olivier Mattelaer, that solved my question.

Dear Olivier, I have a similar issue, using my private model files for hjj. After installing the patch the production seems to work but I still get some error messages a posteriori when I run MadAnalysis.

Before I go into more details I wanted to make sure I am applying the patch correctly. What I did is download the tarball for the revision 315 that you mention here and do a new madgraph installation with that (pdfs, pythia, madanalysis, model files....). Is this correct? Or is it a simpler way to just apply the patch on my older madgraph installation?

Thanks

Hi,

I was not aware that tarball were available for each version.
That's actually good to know.
That's should be a perfect way to have a correct version actually.
No for the MA5 problem please open a separate issue to not mix the problem.
(especially since this will be assigned to MA5 author and not to me)

Cheers,

Olivier
