Respected authors,
I have been trying to implement the Alternative LRM model, with a bidoublet and two doublet Higgs. I have a term in the scalar potential that looks like \alpha \chi^{\dagger}\tilde{\phi}^{\dagger}\tilde{\phi}\chi in TeX format. Here phi is the bidoublet and chi is a doublet. I'm not sure how to write it using contractions in SARAH.
I have written it as alpha conj[chi] phi conj[phi] chi as a test and it provides the correct mass matrices but I can't calculate the RGEs as it seems that there is a 'disentanglement' error. Please help.

Regarding the disentanglement issue, we have another term in the Lagrangian that looks like \alpha_2 \chi^{\dagger} \phi \phi^{\dagger}\chi and we have written it as alpha_2 conj[chi] phi conj[phi] chi

Hi,
I do not understand \ \alpha_2 chi^{\dagger} \phi \phi^{\dagger}\chi and \alpha \chi^{\dagger}\tilde{\phi}^{\dagger}\tilde{\phi}\chi can be both LR invariant. What precisely do you mean by \tilde{\phi}^{\dagger} ?
Best, Werner

Hi,
as far as I can see all the terms are given in the LRLR models which is one of the LRmodels. You can find the corresponding input files in the folder Models/LRmodels/LRLR

Best, Werner

Thank you a lot.
Best wishes

The model we are trying to implement, has a Higgs bidoublet like the standard LRSM model and two doublet Higgs instead of the two triplets in the standard LRSM.

The LRLR model on the other hand has two doublets, two triplets and three singlet Higgs fields.

The Higgs structure seems vastly different with no bidoublet. Please help.
