Yukawa Unification as a Window into the Soft Supersymmetry Breaking Lagrangian
We study Yukawa unification, including the effects of a physical neutrino mass consistent with the Superkamiokande observations, in a string/D-brane inspired SU(4) ⊗ SU(2) L ⊗ SU(2) R model which allows the most general non-universal scalar and gaugino masses, including the usual D-term contributions which arise in SO(10). We investigate how the tight constraints from rare decays such as b → sγ...
متن کاملPerturbative Unification of Soft Supersymmetry–Breaking Terms
Perturbative unification of soft supersymmetry–breaking (SSB) parameters is proposed in Gauge-Yukawa unified models. The method, which can be applied in any finite order in perturbation theory, consists in searching for renormalization group invariant relations among the SSB parameters, which are consistent with perturbative renormalizability. For the minimal Gauge-Yukawa unified model based on...
متن کاملThe Soft Supersymmetry-Breaking Lagrangian: Theory and Applications
After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of ...
متن کاملSoft Supersymmetry Breaking Parameters and Minimal SO ( 10 ) Unification ∗
The minimal supersymmetric SO(10) model, in which not only the gauge but also the third generation fermion Yukawa couplings are unified, provides a simple and highly predictive theoretical scenario for the understanding of the origin of the low energy gauge interactions and fermion masses. In the framework of the Minimal Supersymmetric Standard Model with universal soft supersymmetry breaking p...
متن کاملYukawa Unification in Moduli-dominant SUSY Breaking
We study Yukawa unification in string models with moduli-dominant SUSY breaking. This type of SUSY breaking in general leads to non-universal soft masses, i.e. soft scalar masses and gaugino masses. Such non-universality is important for phenomenological aspects of Yukawa unification, i.e., successful electroweak breaking, SUSY corrections to the bottom mass and the branching ratio of b → sγ. W...
