Susy breaking soft terms in the supersymmetric Pati-Salam landscape from Intersecting D6-Branes
We investigate the supersymmetry breaking soft terms for all the viable models in the complete landscape of three-family supersymmetric Pati-Salam models arising from intersecting D6-branes on a $\mathbb{T}^6/(\mathbb{Z}_2\times \mathbb{Z}_2)$ orientifold in type IIA string theory.

Zusammenfassung: | We investigate the supersymmetry breaking soft terms for all the viable
models in the complete landscape of three-family supersymmetric Pati-Salam
models arising from intersecting D6-branes on a
$\mathbb{T}^6/(\mathbb{Z}_2\times \mathbb{Z}_2)$ orientifold in type IIA string
theory. The calculations are performed in the general scenario of $u$-moduli
dominance with the $s$-moduli turned on, where the soft terms remain
independent of the Yukawa couplings and the Wilson lines. The results for the
trilinear coupling, gaugino-masses, squared-mass parameters of squarks,
sleptons and Higgs depend on the brane wrapping numbers and the susy breaking
parameters. We find that unlike the Yukawa couplings which remain unchanged for
the models dual under the exchange of two SU(2) sectors, the corresponding soft
term parameters only match for the trilinear coupling and the mass of the
gluino. This can be explained by the internal geometry where the Yukawa
interactions depend only on the triangular areas of the worldsheet instantons
while the soft terms have an additional dependence on the orientation-angles of
D6-branes in the three two-tori. In the special limit of parameter space we
find universal masses for the Higgs and the gauginos. |
