Unification of Gauge Couplings in the E6SSM
نویسنده
چکیده
We argue that in the two–loop approximation gauge coupling unification in the exceptional supersymmetric standard model (E6SSM) can be achieved for any phenomenologically reasonable value of α3(MZ) consistent with the experimentally measured central value.

Gauge Coupling Unification in the Exceptional Supersymmetric Standard Model
We consider the renormalisation group flow of gauge couplings within the so-called exceptional supersymmetric standard model (E6SSM) based on the low energy matter content of 27 dimensional representations of the gauge group E6, together with two additional non-Higgs doublets. The two–loop beta functions are computed, and the threshold corrections are studied in the E6SSM. Our results show that...
متن کاملGravitational correction to running of gauge couplings.
We calculate the contribution of graviton exchange to the running of gauge couplings at lowest non-trivial order in perturbation theory. Including this contribution in a theory that features coupling constant unification does not upset this unification, but rather shifts the unification scale. When extrapolated formally, the gravitational correction renders all gauge couplings asymptotically free.
متن کاملPartly Supersymmetric Grand Unification
It is shown how grand unification can occur in models which are partly supersymmetric. The particle states which are composite do not contribute to the running of gauge couplings above the compositeness scale, while the elementary states contribute the usual large logarithmns. This introduces a new differential running contribution to the gauge couplings from partly composite SU(5) matter multi...
متن کاملCoupling Unifications in Gauge-Higgs Unified Orbifold Models
Supersymmetric gauge theories, in higher dimensions compactified in an orbifold, give a natural framework to unify the gauge bosons, Higgs fields and even the matter fields in a single multiplet of the unifying gauge symmetry. The extra dimensions and the supersymmetry are the two key ingredients for such an unification. In this work, we investigate various scenarios for the unification of the ...
متن کاملImpact of unparticles on asymptotic freedom and unification of gauge couplings
Unparticles charged under a gauge group can contribute to the running of the gauge coupling. We show that a scalar unparticle of scaling dimension d contributes to the β function a term that is (2 − d) times that from a scalar particle in the same representation. This result has important implications on asymptotic freedom and unification of gauge couplings. An unparticle with d > 2, in contras...
