Yukawa Coupling Problem

[waqasahmed]

Dear Florian,

For now I am working on a special model where only Hu generates fermion mass through its vev.
Therefore Yd and Ye are redundant and are removed at the model set-up. In order to generate the
down-type quark and lepton masses we have to add a non-holomorphic soft terms into Lagrangian;

L= Wd conj[SHu].conj[FdR].Fq+We conj[SHu].conj[FeR].Fl

As a result all the fermion masses are proportional to vu rather than vd. The tanbeta is just a parameter
without any physical meaning. The attachment is the model file. We use it to generate SPheno file. However
there is an error for identifying fermion masses:

Model_Data_WNHSSM.f90:1206.2:

YdMZ = (vSM*YdSM)/vd
1
Error: Incompatible ranks 0 and 2 in assignment at (1)
Model_Data_WNHSSM.f90:1207.2:

YeMZ = (vSM*YeSM)/vd
1
Error: Incompatible ranks 0 and 2 in assignment at (1)
Model_Data_WNHSSM.f90:1215.2:

Yd = (vSM*YdSM)/vd
1
Error: Incompatible ranks 0 and 2 in assignment at (1)
Model_Data_WNHSSM.f90:1216.2:

Ye = (vSM*YeSM)/vd
1

It seems we still need Yd and Ye to generate fermion masses. Do you know how to solve this problem?

I guess you have not adjusted the matching conditions? See http://stauby.de/sarah_wiki/index.php?t ... _in_SPheno

Dear Florian,

Thanks for your reply. I and my collaborator Bin try to solve this problem, according to your suggestions but not succeed. Here I attached my whole model files. Please look the model files and if you have some other suggestion let us know.

Thanking you,
Best regards,
Waqas

Hi,

I'm sorry but what you are doing there is very dangerous: you add hard SUSY breaking terms to your Lagrangian. I can't recommend to handle this model as SUSY model with SARAH (from a practical as well as conceptional point of view) because the RGEs for dimensionless parameters (i.e. gauge and Yukawa couplings) will for sure not be correct. If you really want to study such a model you need to implement it as non-SUSY models with all potential terms of the component fields written down explicitly.

Best,
Florian

Dear Florian,

Thanks for your guide line. I discuss with my collaborators and they ask to me to write a spheno at low scale for NHSSM model. I write a spheno.m but I have a error when i run the code. Could you please tell me how to solve this problem. I also attached my model files with this email.

Hi,

for a low-scale version you need to define which decays should be calculated (i.e. "=Automatic" is not working). See for instance some non-susy model how this should look like.

Cheers,

Hi Floraian,
'
Hope you are fine and doing well. As you know from my previous email I am working on NHSSM and I want to write Spheno.m file for lowscale. I had try your recommendation but still I have some errors. I attached the Spheno file here. If you find some time and look it where I can do some mistakes. I am very thankful to you.

best regards,
Waqas

Hi,

at first glance, there are (at least) two severeproblems: you haven't defined matching conditions (this is necessary since SARAH 4.10., see
http://stauby.de/sarah_wiki/index.php?t ... _in_SPheno), and you put parameters in MINPAR which are not scalar but matrices (use LHInput as for T').

Cheers,
Florian

Dear Florian,

I try your suggestion for both MSSM and NHSSM model at low scale. But now I have the following errors in both models. Here I paste the error for MSSM. I attached both models Spheno.m files. Could you please look my Spheno.m file and tell me how i solve this problem.

Best regards,
Waqas

Hi,

I can't reproduce the problem. I guess it's more a compiler issue and there is some conflict with different versions you tried to compile. You can try to run

Code: Select all

make cleanall

and compile everything from scratch.

Cheers.
Florian
