Description
We will talk about simplified MSSM models for light neutralinos and charginos with realistic
mass spectra and realistic gaugino-higgsino mixing, that can be used in experimental searches
at the LHC. The formerly used naive approach of defining mass spectra and mixing matrix elements
manually and independently of each other does not yield genuine MSSM benchmarks. Therefore,
we suggest the use of models, whose mass spectra and mixing matrix elements are the result of
a proper matrix diagonalisation. We scan over only the four relevant parameters $\{\mu, \tan \beta,
M_{1}, M_{2}\}$ for a grid of neutralino and chargino masses, having defined a measure for the quality of
the fit, that can also include criteria such as a maximal gaugino or higgsino content.
