an issue with MakeSPheno[]

[MailQuestion]

We are trying to build a new non-SUSY model with SARAH/SPheno with three Higgs doublets and we have encountered a problem which we couldn’t resolve ourselves.

Basically, when we run our model file and generate TeX repository with SARAH, it works absolutely fine without any error messages whatsoever. Also, the pdf-file with model content looks perfectly reasonable.

BUT! A trouble happens at a late stage of MakeSPheno[] process. At the level of “Write tree-level decays” it says twice

Not Found conj[VectorW]{hh,conj[VectorW],conj[VectorW]}{hh,VZ,VZ}

which is very strange since (i) no “VectorW” partcle in the model, and (ii) all the vertices generated by SARAH look fine.

Then, probably, related to the same issue, we get some more errors after "Write Function EDM of Leptons” like:

Part::partw: Part 1 of {} does not exist.

Extract::psl1: Position specification {}[[1,1]] in Extract[{{MHm,MHm2,MFe,MFe2,MVWm,MVWm2,MVZ,MVZ2},{MFd,MFd2,MFu,MFu2},{MFd,MFd2,MFe,MFe2,MFu,MFu2,Mhh,Mhh2,MVZ,MVZ2,MHm,MHm2,MVWm,MVWm2},{MFd,MFd2,MFe,MFe2,MFu,MFu2,Mhh,Mhh2,MVZ,MVZ2,MHm,MHm2,MVWm,MVWm2},{MFu,MFu2,MFd,MFd2,MFe,MFe2,MHm,MHm2,Mhh,Mhh2,MVWm,MVWm2,MVZ,MVZ2}},{}[[1,1]]] is not applicable.

This error disappears when we remove the SM Higgs “hh” from the “ListDecayParticles” so probably there is some bug in the Higgs decay (but then the code can’t work since it requires the Higgs decay).

Hi,

you need to define in particles.m what the W-boson is, e.g

Code: Select all

{VWp,{      Description -> "W+ - Boson", 
...}}, 

Or just "W-Boson" if you defined the state with negtive charge.

Cheers,
Florian

Thanks a lot, Florian! It works!
