Abstract. High-precision analyses of supersymmetry parameters aim at reconstructing the funda-
mental supersymmetric theory and its breaking mechanism. A well defined theoretical framework
is needed when higher-order corrections are included. We propose such a scheme, Supersymmetry
Parameter Analysis SPA, based on a consistent set of conventions and input parameters. A repos-
itory for computer programs is provided which connect parameters in different schemes and relate
the Lagrangian parameters to physical observables at LHC and high energy e+e- linear collider
experiments, i.e., masses, mixings, decay widths and production cross sections for supersymmetric
particles. In addition, programs for calculating high-precision low energy observables, the density
of cold dark matter (CDM) in the universe as well as the cross sections for CDM search exper-
iments are included. The SPA scheme still requires extended efforts on both the theoretical and
experimental side before data can be evaluated in the future at the level of the desired precision.
We take here an initial step of testing the SPA scheme by applying the techniques involved to a
specific supersymmetry reference point.
Here’s what’s next.
