Hi Florian:

I want to construct a Non-Universal Gaugino Masses NMSSM In Gravity Mediation. I introduced three free parameters of the UV input. And the Soft SUSY Parameters From Gravity Mediation at GUT scale just depend on these three free parameters. I want to get the spheno code of this scenario. i just add these three parameters on MINPAR block in SPheno.m file like follows.
MINPAR={
{1,m0},
{2,m12},
{3,TanBeta},
{5,Azero},
{6,F24M},
{7,v24M},
{8,TM}
};

Then i get the spheno code . For runing spheno code , i add Block MSD2IN, MSE2IN, MSL2IN, MSQ2IN, MSU2IN, TDIN, TEIN, TUIN, MSOFTIN, NMSSMRUNIN in LesHouches.in.NMSSM file .


So Do I need to change more places in SPheno.m file and the generated fortran source code ?

Hi,

sorry, it's not exactly clear to me what you want to do:
why do you add the new parameters in MINPAR without using them in the boundary conditions afterwards?

Cheers,
Florian

Dear Florian:

I scan the new parameters' space , and the boundary conditions are the output value.

Sorry, it's still not clear to me what you want to do. Do use the new parameters somewhere else in SPheno.m?
Anyways, if the code runs for you and the results as expected, then go ahead. Otherwise, please be more specific with your question.

Cheers,
Florian

Dear Florian:
Thank you very much for your quick reply.
I'm terribly sorry 。 I didn't make the problem clear.

When i run the code , i can't generate right spectrum file.
Some warning always in Messages.out like follows:
Problem in rkqs, stepsize underflow

ErrorLevel, Iname: -1 1
The error has occured in the following chain of subroutines:
FirstGuess
runRGE
odeint
rkqs
rge218
ParametersToG218


I wonder if spheno can’t recognize the boundary conditions blocks that I added manually in LesHouches.in.NMSSM file ?

Looking at your input, there are many issues:

1) TanBeta=0 doesn't because the leads to an Yukwas coupling which is infinity
2) lambda and kappa a very large; if you set them at the low scale, they run for sure in an Landau pole
3) mu=0 doesn't work either because it gives a massless chargino
...

Since all of this is are physical problems, we should stop the discussion here. The forum is supposed to give only support to technical problems. Everything else goes well beyond would I could provide...

Dear Florian:

Thank you very much。
