SUSY model building for a 126 GeV Higgs
Moritz Mcgarrie
(DESY)
Abstract:
This talk will explore two possible models which can achieve the correct Higgs mass and still allow for sparticles accessible to the LHC's reach. In the first example we built two tailor made spectrum generators to analyse a Higgs extension (non decoupled D-terms) of the MSSM, based on quiver gauge theories. We then explore the LHC & ILC's capability to determine their effect through their enhancement of Higgs branching ratios with respect to the Standard Model. In the second model, we use the NMSSM to obtain the correct Higgs mass and then explore flavour-gauge mediation to obtain light 3rd generation squarks, whilst keeping the 1st and 2nd generation above exclusions. Both models are also realisable through magnetic SQCD. I will hopefully also discuss further avenues for model building opportunities in the context of Natural SUSY.

Eta-deformed AdS5 x S5
Sergey Frolov
(Trinity College, Dublin)
Abstract:
We determine the bosonic part of the superstring sigma model Lagrangian on eta-deformed AdS_5 x S^5, and use it to compute the perturbative world-sheet scattering matrix of bosonic particles of the model. We then compare it with the large string tension limit of the q-deformed S-matrix and find exact agreement. We comment on the structure of the RR sector of the type IIB SUGRA background.
