Hi,
I am using the SARAH-SPheno output and calculate the MSSM Mass at EWSB. Here I am getting the neutralino as lightest particle.
Is there any way to calculate from this program that how much WINO, BINO, Higgsino are contributing in Neutralino.
Thanks for your suggestion

SPheno gives all rotation matrices in the spc file in the SLHA2 conventions. That's all you need.

Cheers
Florian
