I will discuss the motivations and phenomenology of supersymmetry with extra vector-like matter,
including corrections to the Higgs mass, precision electroweak constraints, and collider constraints and signatures.

Model
We discuss the low-energy phenomenology of E6-inspired SUSY GUTs with
an intermediate-scale breaking. These models have TeV scale exotic particles
beyond the MSSM like a Z' boson and leptoquark states. Our focus lies on the
investigation of the parameter space of these models, the specifics of their
spectra as well as their possible LHC phenomenology. We especially discuss
the search and...

Model
The constrained Exceptional Supersymmetric Standard Model (cE6SSM) is an E6 inspired model, where the matter content fills three generations of E6 multiplets at low energies (predicting exciting exotic matter such as diquarks or leptoquarks) and has a universal scalar mass m0 , trilinear mass A and gaugino mass M1/2 at the GUT scale. If some or all of these particles are discovered at the LHC...

Model
We consider the relations between the gauge couplings at the electroweak scale
and the high scale where unification of the three gauge couplings is expected.
Threshold corrections are incorporated both at the supersymmetric and at the grand
unified scale and, where available three-loop running and two-loop decoupling are
employed. We study the impact of the current experimental...

Model
We study cascade textures in supersymmetric grand unified theories. The neutrino Dirac mass matrix of the cascade form can lead the tri-bimaximal generation mixing at the leading order in the seesaw mechanism while the down quark mass matrix of a hybrid cascade form naturally gives the CKM structure. We embed such experimentally favored mass textures into SUSY GUT, which gives relations...

Model
We describe the SU(3)xSU(2)xU(1)_Y gauge theory without resorting to an intermediate unification group.
Its group is the commutant to a structure group SU(5) x U(1)_Y of a gauge bundle in E_8. The spectrum contains three generations of quarks and leptons plus vectorlike electroweak and colored Higgses. The minimal MSSM Yukawa couplings with matter parity is obtained at the renormalizable level.
