The Minimal Supersymmetric Standard Model (MSSM) can include two softbreaking terms which are often neglected: a non-analytic scalar trilinearcoupling and a Higgsino bilinear term. A set of high-scale boundary conditionsconsistent with the reparameterisation invariance which the model possesses isobtained. The three-family renormalisation group equations for the MSSM withthese terms are presented. The ranges of the universal high-scale values ofthese couplings which lead to an acceptable TeV-scale theory are obtained, asis the supersymmetric particle spectrum at this scale. The effect of the newterms on fine-tuning is presented. SOFTSUSY, an existing program forcalculating SUSY particle spectra, has been used, with as few modifications aspossible.Comment: 23 pages, 9 figures (Two new references and one corrected reference.
