ttbar FCNC using Madgraph5

Looks like that one of the process definitions that you use is not defined in your model.

I guess that this is one of the madspin decay. Just try to generate those ones inside MG5aMC to see which one does not exists.

Hi Oliver,

Thank you for your help and advice. I generated all of these process, but using the "Loading default model: sm" since NP = 0.
They seem to work as intended but the problem comes arises when FCNC top decays are included. Does the model used has some problem or there is something else.

generate p p > t t~ NP=0 @10
add process p p > t t~ j NP=0 @11
add process p p > t t~ j j NP=0 @12
add process p p > t t~ j j j NP=0 @13

Hi,

> Does the model used has some problem or there is something else.

I do not know your model, so I can not comment on that (neither test your stuff on my machine).
But yes my guess is that your list of command is not compatible with your model.

Cheers,

Olivier

Hi Again,

Thank alot for your comments, Just to elaborate a bit more. I am generating only one process: p p > t t~ NP=0 @10 and using the model:

MG5_aMC>import model TopFCNC_UFO-all_ProdConventions_no_b_mass --modelname

but it still complains, I think this should work on any machine to reporduce the error. Your comments/suggestions would be highly appreciated.

Hi Jack,

The model that you are using is not part of MG5aMC, not in the official list of model that we can auto-download from the FeynRules website. So no I can not (even try to) reproduce your problem.

As said above, your problem is likely that
generate t > h c NP=1 does not return any Feynman Diagram.

If that's a bug of the model or of our framework, I can not tell since I do not know if such coupling exists in your model (and/or if it is zero or not for your restrict_all_ProdConventions_no_b_mass file)

Cheers,

Olivier

Hi Oliver,

Thank you for your feedback. I was looking for a repo where I can find the model and you have access to it. So here is the model tar:
https://cms-project-generators.web.cern.ch/cms-project-generators/TopFCNC_patch4_UFO.tgz

model: import model TopFCNC_UFO-all_ProdConventions_no_b_mass --modelname
process: generate p p > t t~ NP=0 @10
madspin:
decay t~ > w- b~, w- > j j NP=0
decay t > h c NP=1

Thanks in advance.

Hi,

Ok the problem originates in the computation of the partial width since MadSpin needs to know it
in order to normalise correctly the cross-section.

The problem is that the evaluation of the width is 0.00761819968536
which is lower than the QCD scale and therefore the tools that we use to compute the width put that width to zero.
This actually makes a lot of sense since such decay is actually occuring after the hadronization of the particle
and therefore you should not trust such result.

Cheers,

Olivier

Hi Oliver,

So, what is the solution to it, how to stop the tool not to put the width equal to zero. Previously, this model
has been used for the generation in previous versions of Madgraph.

Thanks in advance.

Hi,

> Previously, this model
> has been used for the generation in previous versions of Madgraph.

It is not because it has been done before that it such generation makes sense.
In that regime you can not trust perturbative QCD...
Therefore you can not use our tool to have a sensitive result for such decay.
(At least I believe that)

> So, what is the solution to it, how to stop the tool not to put the width equal to zero

Well the solution should be different.
But if you do not think that using perturbative QCD is not a problem here what you can do
is to bypass the automatic computation of the width by providing yourself the total width and branching ratio.
I will not trust the result of that simulation but this is your responsibility not mine.
Please remember to specify such issue in any publication (and the associate justification why you think that it is fine)

Cheers,

Olivier
