Large D-terms in minimal SUSY SO(10)

Presented by Mr. Tomas GONZALO on 22 Jul 2014 from 14:30 to 14:50

After the first run of the LHC and the last results on direct supersymmetry searches from ATLAS and CMS, the lack of evidence of new particles is causing some tension for several minimal models of supersymmetry. The current limits push the masses of most supersymmetric particles above the TeV scale, which requires a troubling amount of fine tuning in order for SUSY to be a solution to the stability of the Higgs mass. However, moving away from the simplest models, one can find regions of parameter space where these limits are relaxed, such are scenarios with a compressed spectrum or where part of the spectrum is decoupled. Using a simple SUSY SO(10) model, one can obtain these type of scenarios in a very natural way. The splitting provided by use of the SO(10) D-terms can be exploited to obtain very light third generation squarks, light enough to be quasi-degenerate with the LSP and thus fall into the compressed spectrum scenarios, which do not suffer from high levels of fine tuning and whose limits are much less constrained that other models. In this presentation I will discuss the effect of large D-terms in the well motivated minimal SUSY SO(10) model which can predict a viable MSSM spectrum that survives the current exclusion limits provided by the LHC experiments.
