Open AccessA realistic theory of E6 unification through novel intermediate symmetries
We propose a non-supersymmetric E6 GUT with the scalar sector consisting of 650 ⨁ 351′ ⨁ 27. Making use of the first representation for the initial symmetry breaking to an intermediate stage, and the latter two r...

Open AccessTrinification from E6 symmetry breaking
In the context of E6 Grand Unified Theories (GUTs), an intriguing possibility for symmetry breaking to the Standard Model (SM) group involves an intermediate stage characterized by either SU(3) × SU(3) × SU(3) (t...

Open AccessHolographic thermal propagator for arbitrary scale dimensions
Using the AdS/CFT correspondence we model the behaviour of the two-point correlator of an operator with arbitrary scale dimension ∆ in arbitrary spacetime dimension d for small but non-zero temperature. The obtai...

Open AccessKutasov-Seiberg dualities and cyclotomic polynomials
We classify all Kutasov-Seiberg type dualities in large Nc SQCD with adjoints of rational R-charges. This is done by equating the superconformal index of the electric and magnetic theories: the obtained equation ...

Open AccessResurrecting minimal Yukawa sector of SUSY SO(10)
Supersymmetric SO(10) models with Yukawa coupling matrices involving only a 10H and a ...

Open AccessSafe SUSY
We investigate the short distance fate of distinct classes of not asymptotically free supersymmetric gauge theories. Examples include super QCD with two adjoint fields and generalised superpotentials, gauge th...

Open AccessYukawa sector of minimal SO(10) unification
We show that in SO(10) models, a Yukawa sector consisting of a real 10H, a real 120H and a complex 126H of Higgs fields can provide a realistic fit to all fermion masses and mixings, including the neutrino sector...

Open AccessAsymptotically safe grand unification
Phenomenologically appealing supersymmetric grand unified theories have large gauge representations and thus are not asymptotically free. Their ultraviolet validity is limited by the appearance of a Landau pol...

Open AccessResurrecting the minimal renormalizable supersymmetric SU(5) model
It is a well-known fact that the minimal renormalizable supersymmetric SU(5) model is ruled out assuming superpartner masses of the order of a few TeV. Giving up this constraint and assuming only SU(5) boundar...

Open AccessR-parity violation in SU(5)
We show that judiciously chosen R-parity violating terms in the minimal renormalizable supersymmetric SU(5) are able to correct all the phenomenologically wrong mass relations between down quarks and charged l...

Open AccessTowards the minimal renormalizable supersymmetric E 6 model
We find an explicit renormalizable supersymmetric E 6 model with all the ingredients for being realistic. It consists of the Higgs sector

Open AccessSupersymmetry breaking induced by radiative corrections
We show that simultaneous gauge and supersymmetry breaking can be induced by radiative corrections, à la Coleman-Weinberg. When a certain correlation among the superpotential parameters is present, a local sup...
