Re: Change the input parameters in LesHouches.in.BLSSMIS_low

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

Re: Change the input parameters in LesHouches.in.BLSSMIS_low

Hi Florian, May I ask why in MSSM\SPheno.m the BoundaryLowScaleInput are { {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]]} }; Whil...

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 sol...

Re: Loop level

Hi,

You mean i can generate in Flavour Kit two- loop diagrams ? i think i have to modify the 2d2L.m file , should i use Filters or what ?
because in default it generates only one loop - diagrams ..

Thanks ..

Loop level

Hi Florian,

I read in the manual of the FlavorKit that the Wilson coefficients are calculated on one 1- loop level ..
I wonder can calculations made also on 2-loop level, for instance get two penguins in b -> s l+ l- decay ?

Best.

Error in LesHouches.in.MSSM.low

Hi Florian, I filled a LesHouches.in.MSSM.low with arbitrary benchmark at low scale. I made scan on this benchmark and i know it's working , but however when i run LesHouches.in.MSSM.low in SPheno , it gives the following error Calculating mass spectrum 1 .-iteration NaN appearing in CouplingcUFdGlu...

Running of the Wilson Coefficient with energy scale

Dear sir,

I can run in SARAH the gauge couplings constants versus energy scale by using RunRGEs[] . Can one similarly check the dependence of the calculated Wilson Coeff. in spc file on the energy scale \mu ?

Thanks .
