Simplified SUSY models with different mixing cases

Hi

Probably a bit technical, but here it is.

I am trying to construct some simplfied SUSY models (that is, you only tune the masses of the core process, while all the rest are decoupled), and I would like to play with different mixing scenarios for the neutralino and charginos, so to get a more bino-like or wino-like scenario.

Now, the mixing is basically depicted in the .slha one can use in the UMIX,VMIX and NMIX blocks, but given that the actul structure of the matrix is not trivial to calculate by hand (in contrast for example if you want to get the mixing for top-squark, where you only need the theta_mixing and you can easily get the block for the .slha), I was wondering if someone has a hint how to get blocks for max, min and no_mixing between chargino and neutralinos, so to then generate events with Pythia

Thanks in advance

Alex
