Dear all,

I have been trying to implement the following model (arXiv 1012.5105, 1212.4428) in SARAH. However, the superpotential of the model has 4 superfield interactions like 1/M_R Y_v s1.L.Hu.N where MR is a large mass scale and Yv is the Yukawa coupling responsible for generating neutrino masses. Is it possible to define such a term in SARAH ? If yes, how can I define that large MR mass scale correctly in SARAH ? I get the following error messages once I try to generate SPheno Source Code:
"CheckModelFiles: The following parameters are not defined in ParameterDefinitions in parameters.m: {Q[Yv]}"
"CheckModelFIles: For the following parameters is no OutputName defined: {Q[Yv]}"

Thanks in advance,
Ozer

Hi,

Q[Yv] is just the soft-breaking counter-part of Yv (i.e. a four scalar interaction ). If this is your only warning, the part concerning neutrino masses might work. You can also take a look in the Seesaw models delivered with SARAH which also contain the Weinberg operator.

Cheers,
Florian

Hi,
I want to calculate the quartic interctions of the charged Higgs in THDM model using the coamand
1. Simplify[GetScatteringDiagrams[{Hpm, Hpm} -> {Hpm, Hpm}] /. {tChan -> 0, uChan -> 0, qChan -> 1, sChan -> 0, conj[Subscript[\[Lambda], 5]] -> Subscript[\[Lambda], 5]}]
2. Simplify[GetScatteringDiagrams[{Hpm, conj[Hpm]} -> {Hpm, conj[Hpm]}] /. {tChan -> 0, uChan -> 0, qChan -> 1, sChan -> 0, conj[Subscript[\[Lambda], 5]] -> Subscript[\[Lambda], 5]}]

I am getting ZERO. Also it is true for any model having extra charged particles. Why? Am I doing anything wrong?

Please help me to understand this..
NB:
I getting exact result for hh hh > hh hh
Simplify[GetScatteringDiagrams[{hh, hh} -> {hh, hh}] /. {tChan -> 0, uChan -> 0, qChan -> 1, sChan -> 0, conj[Subscript[\[Lambda], 5]] -> Subscript[\[Lambda], 5]}]
