Nature of problem:
The determination of sparticle masses and couplings of SUSY particles in the R-parity conserving MSSM is the basic problem. Low energy data on Standard Model fermion masses, gauge couplings and electroweak boson masses are to be used as a constraint. SUSY radiative corrections from sparticle loops to these inputs depend upon the sparticle spectrum, and must be calculated. Theoretical constraints on the SUSY breaking parameters from a higher theory are often imposed at a high renormalisation scale, perhaps resulting from a supergravity or string theory. Finally, the MSSM parameters must also be consistent with a minimum in the Higgs potential which leads to the observed electroweak boson masses.
The renormalisation connecting a high scale and the electroweak scale is calculated by the Runge-Kutta method. Iteration then provides a solution consistent with the multi-boundary conditions.
