• Change the input parameters in LesHouches.in.BLSSMIS_low

Dear Florian,

I found that the LesHouches.in.low file generated for MSSM has the Block EXTPAR as:

1    1.51818488E+02  # M1input
2    2.91697911E+01  # M2input
3    5.86587210E+02  # M3input
23   1.08920000E+01   # Muinput
24   .50000000E+05   # MA2input
25   2.50000000E+01    # TanBeta

i,e, with \mu and mA as inputs to solve the tadpole equations. But however of BL-SSM-IS the generated LesHouches.in.low file has mHu and mHd instead as input, so may i ask how to make modification in LesHouches.in.BLSSMIS_low , to add \mu and mA like in case of MSSM ?

I tried to do this:

Code: Select all

Block MSOFTIN       #  
   1    1.17323743E+03  # M1
   2    1.97096680E+03  # M2
   3    5.04714494E+03  # M3
Block EXTPAR      # Input parameters 
23   1.08920000E+01   # Muinput
24   .50000000E+05   # MA2input

But it gives this error when running in SPheno:

Code: Select all

 No consistent solution found for tadpoles: 
 Negative absolute squared: ,Abs2Mu 
 Result:   -4157.6895038449993

Thanks ..

All of that depends on SPheno.m, and is explained in detail at http://stauby.de/sarah_wiki/index.php?t ... properties

Thank you, first time to learn about ..

Hi Florian,

May I ask why in MSSM\SPheno.m the BoundaryLowScaleInput are

Code: Select all

{
 {MassB, M1input},
 {MassWB, M2input},
 {MassG, M3input},
 {\[Mu], Muinput},
 {B[\[Mu]], mA2input/(TanBeta + 1/TanBeta)},
 {vd,Sqrt[4 mz2/(g1^2+g2^2)]*Cos[ArcTan[TanBeta]]},
 {vu,Sqrt[4 mz2/(g1^2+g2^2)]*Sin[ArcTan[TanBeta]]}
};

While in BLSSMIS the BoundaryLowScaleInput are

Code: Select all

  
  {vd,Sqrt[4 mz2/(g1^2+g2^2)]*Cos[ArcTan[TanBeta]]},
 {vu,Sqrt[4 mz2/(g1^2+g2^2)]*Sin[ArcTan[TanBeta]]}
};

Actually I modified the SPheno.m of BLSSMIS to set the solution of the tadpole equation to \mu and MA^2 as in MSSM ,
please see the attached file, you will find that i added

Code: Select all

ParametersToSolveTadpolesLowScaleInput = {mHd2,mHu2};

as explained in the online manual ..
then i added BoundaryLowScaleInput as in MSSM..

The problem now i don't know weather the last step is right or wrong, because after running the model in SPheno , the LesHouches.in.BLSSMIS_low starts to show warnings about calculations of negative mass squared when starting Calculating low energy constraints ..

So i will be grateful , if you told me your comments ..

I attached also the LesHouches file

Astro

You can't use two parameters to solve four equations.

Hi,

Now I changed the tadpole equations line in BLSSMIS\Spheno.m as:

Code: Select all

ParametersToSolveTadpoles = {mHd2,mHu2,mC12,mC22};

So i understand like that Spheno will solve the equations for mhd2, mhu2, mc12, mc22 and requires \mu, Bmu, Mup, and B[Mup] as inputs ..
I didn't add any thing else to Spheno.m

Please may you look at the attached LesHouches.in_low file , actually at as expected, but however still when running in Spheno gives warnings about negative mass squared of scalar fields when calculating the low scale constrains ..

Please let me your comments, is these warnings due to some thing wrong Spheno.m file or in the LesHouches file ?

Thanx
