ABSTRACT
We have seen in Chapter chapter3 that spontaneous SUSY breaking through a non-vanishing F- or D-term leads to a phenomenological problem, namely the existence of tree level sum rules for the mass squares: STr M 2 = 0 , ⇒ Tr M scalars 2 = 2 Tr M fermions 2 . $$ \begin{aligned} \mathrm{STr} \mathcal{M}^2 =0, ~~~ \Rightarrow ~~~ \mathrm{Tr} M_{\mathrm{scalars}}^2 = 2 \mathrm{Tr} M_{\mathrm{fermions}}^2. \end{aligned} $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315367903/c2682a74-a79a-4ae8-b55f-fb03894f6bcd/content/math16_1.tif"/>
