Error running madspin - KeyError : ((-5, 21), (-6, -5, 6))

Did you try the latest version?

Hi Olivier,

Thank you for your fast reply.

I am doing it in the athena, so the release I was using was atlas related v2_6_2_atlas2 (LCG)
Now I tried to do with another version which is v2_3_3_p1
and it showed me another error

Command "launch" interrupted with error:
 KeyError : ((21, 21), (-13, -12, -5, 5, 11, 14, 21))
 Please report this bug to developers
More information is found in 'MS_debug'.
Please attach this file to your report.

Maybe the versions I am using are not the right ones?

Thanks,
anna
Anna

Can you try with 2.6.3.2 ?
MadSpin had a lot of instabilities in the last couple of version and you really need that version to be sure that MadSpin is working.

Cheers,

Olivier

Hi Oliver,

I have tried to use the version you have told me. The error appears the same.

Before using the madspin I am using the Powheg. for pp->ttbar. And then I use the madspin for a decay.
I was told before that this error can be from the fact that I use powheg first and that when madspin tries to find all decays it also have decays with b quarks, but powheg doesn't have it. However, nobody could tell me how I could fix the madspin in this case. I tried to set the mass of b quark to zero and later in the model itsel using restrict_no-bmass, and then later put to its value in the param_card, but I do not know whether this is a good approach or not.

Do you have may be other ideas?

The error is below. Do you need may be the MS_debug as well?
Thanks you,
Anna

Hi,

I have actually never use MadSpin in conjunction of POWHEG.
Even if indeed nothing prevents it (and I do not want to prevent it).

The trick to use event from other generator than MG5aMC is to have a MG5aMC banner in the top of the events file since madspin reads
1) the mg5proccard part of the header
2) the slha part of the banner

So this error indicate that your mg5proccard is not valid since you are likely to have not include some of the matrix-element that you need.
From the log, you are at least missing the following matrix-element:
5 21 > 6 -6 5 matrix element (i.e. b g > t t~ b)
So you have to add it in a way (or another) in the mg5proccard.

They are many possible syntax that you can use
in principle adding there
add process 5 21 > 6 -6 5

Cheers,

Olivier

Hi Olivier,

Thanks for the suggestions.
I think I had what you said
1) the mg5proccard part of the header
2) the slha part of the banner

And then I added the process as you suggested. However, the error is still there.
I just noticed one thing, that when it loads the 2HDMtypeII model it has the following:

generate 08:24:19 INFO: detected model: /cvmfs/atlas.cern.ch/repo/sw/Generators/madgraph/models/latest/2HDMtypeII. Loading...

So here I see there is no b quarks. Later on I change the definition of the p and j
define p = g u c d b s u~ c~ d~ s~ b~
define j = g u c d b s u~ c~ d~ s~ b~

and then I see the following lines:

So looks like it has 4 flavour and not 5. Maybe this is the reason why I am having the problem?
What do you think?

Thanks for helping,

Hi,

> So looks like it has 4 flavour and not 5. Maybe this is the reason why I am having the problem?

Yes that's correct, you need to tell madspin (either via the mg5proccard or via the madspin card)
to use a model which is five flavor (i.e. where the mass is hardcoded to zero).

If you need to modify the model for that you should look at the following method:

Hi Olivier,

Thank you a lot. I saw that in 2HDMtypeII they already have the restriction with no b mass.
I have used it and looks like it processed.
I got some waring:

generate 10:18:59 INFO: Decaying the events...

generate 10:21:09
generate 10:21:09 INFO: Total number of events written: 6050/6050

Is it ok? Sorry, I just want to make sure that it is all right.

Also I wanted to ask you another question. I see that b mass is set to zero as well as the Yukawa mass of b to zero in the restriction. I have p p > t t~, (t~ > b~ w- , w- > l- vl~ ), t > b h+ process and does it mean that later in param card I need to set the Yukawa mass to appropriate value? Or they shall be left untouched?
I also want to pass events through pythia8 and I guess it will use parameters from the decay?

Thank you a lot,
Anna

Hi,

> generate 10:21:09 WARNING: Found many weight larger than the computed max_weight (12/6050 = 0.198347107438%).

This means that the max-weight was under-estimated. and that you can have a small bias due to that.
Since the bias is small, we only put a warning.
You can decide to procede (in any case you have other bias anyway) or you should ask for madspin to
increase the number of points used to compute the max_weight (via the madspin_card)

> I have p p > t t~, (t~ > b~ w- , w- > l- vl~ ), t > b h+ process and does it mean that later in param card I need to set the Yukawa mass to appropriate value?

Well what is the coupling for t > b h+ ? If it is proportional to the yukawa coupling?
You can also decide to set a restriction_card where the yukawa is not zero but where the mass is.
(But do not use feynman gauge/complex mass scheme in that case)

Cheers,

Olivier

Hi Olivier,

Thank you for your help

The best,
Anna
