We make a comprehensive study of the theory and phenomenology of a low energy supersymmetric standard model originating from a string-inspired E 6 grand unified gauge group. The Exceptional Supersymmetric Standard Model (ESSM) considered here is based on the low energy SM gauge group together with an extra Z ′ corresponding to an extra U (1) N gauge… (More)

The Higgs boson spectrum of the Next-to-Minimal Supersymmetric Standard Model is examined. The model includes a singlet Higgs field S in addition to the two Higgs doublets of the minimal extension. 'Natural' values of the parameters of the model are motivated by their renormalization group running and the vacuum stability. The qualitative features of the… (More)

INTRODUCTION
Several blood tests are performed uniformly in patients hospitalized with acute decompensated heart failure and are predictive of the outcomes: complete blood count, electrolytes, renal function, glucose, albumin and uric acid. We sought to evaluate the relationship between routine admission laboratory tests results, patient characteristics and… (More)

We consider the renormalisation group flow of gauge couplings within the so-called exceptional supersymmetric standard model (E 6 SSM) based on the low energy matter content of 27 dimensional representations of the gauge group E 6 , together with two additional non-Higgs doublets. The two–loop beta functions are computed, and the threshold corrections are… (More)

We discuss some phenomenological aspects of an E 6 inspired supersymmetric standard model with an extra U (1) N gauge symmetry under which right-handed neutri-nos have zero charge, allowing a conventional seesaw mechanism. The µ problem is solved in a similar way to the NMSSM, but without the accompanying problems of singlet tadpoles or domain walls. The… (More)

We review symmetries protecting a zero value for the cosmological constant in no–scale supergravity and reveal the connection between the Multiple Point Principle, no–scale and superstring inspired models .

We calculate flavour dependent lepton asymmetries within the E 6 inspired Super-symmetric Standard Model (E 6 SSM), which has an extra U (1) N symmetry. In this model, the right-handed neutrino doesn't participate in gauge interactions, allowing it to be used for both the see–saw mechanism and leptogenesis. Extra Higgs, leptons and leptoquarks predicted by… (More)

The tiny order of magnitude of the cosmological constant is sought to be explained in a model involving the following ingredients: supersymmetry breaking in N=1 supergravity and the multiple point principle. We demonstrate the viability of this scenario in the minimal SUGRA model.

In this talk we argue that the breakdown of global symmetries in no–scale supergravity (SUGRA), which ensures the vanishing of the vacuum energy density near the physical vacuum, leads to a natural realisation of the multiple point principle (MPP). In the MPP inspired SUGRA models the cosmological constant is naturally tiny. 1. No-scale supergravity and the… (More)

On the origin of Z 2 symmetry in the Two-Higgs Doublet extension of the SM. Abstract We argue that the consistent implementation of the multiple point principle (MPP) in the general non-supersymmetric two Higgs doublet model (2HDM) can lead to a set of approximate global custodial symmetries that ensure CP conservation in the Higgs sector and the absence of… (More)
