Universality<br />
Reduces number of <strong>SUSY</strong> breaking parameters from<br />
100 to 3:<br />
• tan β ≡ v 2 /v 1<br />
• m 0 , the common scalar mass (flavour).<br />
• M 1/2 , the common gaugino mass (GUT/string).<br />
• A 0 , the common trilinear coupling (flavour).<br />
These conditions should be imposed at<br />
M X ∼ O(10 16−18 ) GeV <strong>and</strong> receive radiative<br />
corrections<br />
∝ 1/(16π 2 ) ln(M X /M Z ).<br />
Also, Higgs potential parameter sgn(µ)=±1.<br />
