new model implementation fails to be processed to spheno

[FStaub]

You need to define in parameters.m that RS is your mixing matrix for Higgs scalars as it done by default for other models, e.g. in the MSSM

Code: Select all

{ZH,        { Description->"Scalar-Mixing-Matrix"}},

Hi,

Thanks !!

Hopefully the final one:

I get compilation errors because dSinTW, -dCosTW are not defined in OneLoopDecays_Anomalyfree.f90

But they are defined in spheno.m

RenConditionsDecays={
{dCosTW, 1/2*Cos[ThetaW] * (PiVWm/(MVWm^2) - PiVZ/(mVZ^2)) },
{dSinTW, -dCosTW/Tan[ThetaW]},
{dg2, 1/2*g2*(derPiVPheavy0 + PiVPlightMZ/MVZ^2 - (-(PiVWm/MVWm^2) + PiVZ/MVZ^2)/Tan[ThetaW]^2 + (2*PiVZVP*Tan[ThetaW])/MVZ^2) },
{dg1, dg2*Tan[ThetaW]+g2*dSinTW/Cos[ThetaW]- dCosTW*g2*Tan[ThetaW]/Cos[ThetaW]}
};


Any clue ?

Best,

Well, in your model you don't have any longer the angle ThetaW because you don't give any parametrisation of your extended vector boson rotation matrix. Therefore, this definition of the Counter-Terms is not consistent.
The simplest option is to remove just the definition of the counter-terms in SPheno.m because I guess you don't need one-loop corrections to two-body decays where the ew sector is renormalised on-shell, or? You can also turn off the entire output of the loop corrected decays via the corresponding option of MakeSPheno.

Hi Florian,


Thanks !!

I have been able to create the spheno version and compile it.

I have a general question about the spheno version created
by SARAH in general.

Does spheno check whether the EW minimum it computes
is a global one (ie they are other minimum with trivial vevs
that could be global ones and the point should be ruled out) ?


Best,

Hi,

No, SPheno doesn't check that. However, you can pass the spc file to vevacious which searches for the minimum of the one loop potential.

Cheers
