complex parameters not exported to UFO in feynrules

Asked by Ilaria Brivio on 2018-01-18

Hi,

I seem to have a very weird problem with Feynrules. I realized that none of the UFO models exported for SMEFTsim-set A
http://feynrules.irmp.ucl.ac.be/wiki/SMEFT
contain the complex conjugates of complex Wilson coefficients.

I am running some tests with the latest version of Feynrules 2.3.29 and the operator OuW in the U3^5 symmetric model.

The Lagrangian is just

cuW OuW + Conjugate[cuW] HC[OuW]

with these definitions:

[from SMEFTsim_A_operators_U35.fr]

OuW:= Block[{sp1,sp2,mu,nu,ii,jj1,jj2,kk,cc,ff1,ff2},
 feynmangaugerules = If[Not[FeynmanGauge], {G0|GP|GPbar ->0}, {}];
 ExpandIndices[QLmbar[sp1,ii,ff1,cc].uR[sp2,ff2,cc] Conjugate[yu[ff2, ff1]] sigmaT[mu,nu,sp1,sp2] PauliSigma[kk,ii,jj1] Eps[jj1,jj2] Phibar[jj2] FS[Wi,mu,nu,kk] , FlavorExpand->{SU2W,SU2D}]/.feynmangaugerules/.redefCtoZero
 ]//OptimizeIndex;

[from d6_parameters_U35.fr]

  cuWPh == {ParameterType -> External, Value -> 0, ComplexParameter -> False},

  cuWAbs == {
    ParameterType -> External,
    Value -> 1,
    InteractionOrder -> {NP, 1}
  },

  cuW == {
    ParameterType -> Internal,
    Value -> cuWAbs Exp[I cuWPh],
    ComplexParameter -> True,
    InteractionOrder -> {NP, 1},
    TeX -> Subscript[c,uW]
  },

when I look at the model in Mathematica I see that cuW is complex and the vertices given by FeynmanRules are correct.

However, when I do ExportUFO something goes wrong (see files attached).
cuW is actually treated as a real quantity in the couplings, although the parameter.py file says that it's a complex quantity.

The problem appears to be solved if I write explicitly cuWAbs Exp[I cuWPh] in the Lagrangian, but expanding all the complex coefficients would make the Lagrangian manipulation quite heavy, so I'd prefer to keep the notation compact if possible. (besides, SMEFTsim-setB is coded in a similar way but it doesn't appear to have the same issue, which is quite weird)

Is there something fishy I am doing wrong?

Thanks a lot!
Ilaria

This is the couplings.py I get for the exported UFO

Hi,

This is actually a question (which is more a request actually) for the FeynRules author.
I can only tell you one potential reason of this.

The UFO model wants to have as input a card following the LesHouchesAccord, (like the SLHA ones for examples).
But in that community-wide agreement, all input parameter are supposed to be a real number. Therefore if you want complex parameter it is usual to have two entry in that file (the real part and the imaginary part).

The next LesHouches is actually in two years, so this is probably not going to change soon.

Cheers,

Olivier

Hi Olivier,

thanks. It can be as you say, but the issue is still weird, because this complex parameter is an internal one. in the param card one fixes absolute value and phase, which are real numbers.

The trick works for the CKM and in the other version of SMEFTsim, so I'm just really confused about why it's not interpreted correctly in this case.

Is is possible to pass this on to a Feynrules author?

Thanks again!
Ilaria

Hi,

Feynrules decides to not use the launchpad platform for their support to the user.
In the past they were using a ticket system on their website https://feynrules.irmp.ucl.ac.be but it does not seem active.
So my advice would be that you just send an email to Claude Duhr.

Cheers,

Olivier

Oh, sorry, I thought you could pass it on (I had the impression I had read some FR answers here but maybe that's inaccurate, or just old messages). My bad.
I'll send an email then.

Thanks anyways!
