The weak mixing angle and unification mass in supersymmetric SU(5)

  title={The weak mixing angle and unification mass in supersymmetric SU(5)},
  author={Martin B. Einhorn and D. R. Timothy Jones},
  journal={Nuclear Physics},
We consider the predictions for the weak mixing angle 0w and the scale M of unification in a supersymmetric extension of SU(5). with particular emphasis on the sensitivity to the number of Higgs multiplets. In the one-loop approximation, we also calculate the ratio nrJrn,. We discuss generally the effects of an intermediate threshold between the weak interaction scale and M and estimate the sensitivity of 6’w and M to the scale of supersymmetry breaking The evolution of the coupling constants…

Yukawa coupling unification in non-supersymmetric SO(10) models with an intermediate scale
We discuss the possibility of unifying in a simple and economical manner the Yukawa couplings of third generation fermions in a non-supersymmetric SO(10) model with an intermediate symmetry breaking,
Nucleon decay in the minimal supersymmetric SU(5) grand unification
We make a detailed analysis on the nucleon decay in the minimal supersymmetric SU(5) grand unified model. We find that a requirement of the unification of three gauge coupling constants leads to a
Fermion masses in a supersymmetric SU(4)⊗SU(2)L⊗SU(2)R model
Abstract We calculate quark and lepton masses and quark mixing angles in the framework of a supersymmetric SU(4)⊗SU(2) L ⊗SU(2) R model where the gauge group is broken at 1016 GeV The model predicts
Predictions of SUSY masses in the minimal supersymmetric grand unified theory
The Minimal Supersymmetric Standard Model (MSSM) distinguishes itself from other GUT's by a successful prediction of many unrelated phenomena with a minimum number of parameters. Among them: a)
Low-energy behaviour of realistic locally-supersymmetric grand unified theories
The recently proposed cosmologically acceptable N=1 supergravity models based on the SU(5) unification group define unambigously the minimal particle content of the theory. This fact allows us to
Minimal supersymmetric unification predictions
Abstract We re-examine the predictions for the gauge couplings in the minimal extension of the standard model which result from the assumption that the model comes from a unified theory with a single

Abstract The masses of vector supermultiplet and Higgs supertriplet in the standard supersymmetric SU (5) model are calculated. Taking into account uncertainties related with the initial gauge
Precision corrections to supersymmetric unification
We compute the full set of weak-scale gauge and Yukawa threshold corrections in the minimal supersymmetric standard model, including all finite (non-logarithmic) corrections, which we show to be
Proton lifetime from SU(5) unification in extra dimensions
We provide detailed estimates of the proton lifetime in the context of simple supersymmetric SU(5) grand unified models with an extra compact spatial dimension, described by the orbifold S/(Z_2 x
Quark and Lepton Masses in 5D SO(10)
We construct a five dimensional supersymmetric SO(10) × D3 grand unified model with an S1/(2 × '2) orbifold as the extra dimension. The orbifold breaks half of the supersymmetry and breaks the SO(10)


Grand Unification of Effective Gauge Theories
Abstract An effective non-renormalizable SU(3)×SU(2)×U(1) invariant gauge theory results at ordinary energies when superheavy fields are integrated out from a grand unified theory based on a simple
Uncertainties in the proton lifetime
We discuss the masses of the leptoquark bosons mx and the proton lifetime in grand unified theories based principally on SU(5). It is emphasized that estimates of mx based on the QCD coupling and the
How Accurately Can We Estimate the Proton Lifetime in an SU(5) Grand Unified Model
Abstract We reduce the theoretical uncertainties in the prediction of the proton lifetime in the simplest SU(5) model to an uncertainty reflecting our lack of precise knowledge of the QCD coupling
Hierarchy of interactions in unified gauge theories
We present a general formalism for calculating the renormalization effects which make strong interactions strong in simple gauge theories of strong, electromagnetic, and weak interactions. In an
Softly Broken Supersymmetry and SU(5)
We construct an explicit realistic SU(5) model in which softly broken supersymmetry is used to protect the Higgs doublets from quadratic mass renormalization. The model requires one natural but
Generalized Gauge Hierarchies
We generalize the analysis of coupling-constant renormalization in unified theories to allow for more than one scale of spontaneous symmetry breakdown between unification and SU(3)
Effective gauge theories
A method is described for dealing with gauge field theories that contain very heavy particles, by constructing a gauge-invariant effective field theory, in which the heavy particles do not appear.
Asymptotic behaviour of supersymmetric Yang--Mills theories in the two-loop approximation
Abstract A calculation of the renormalisation group function β ( g ) to O( g 5 ) for a supersymmetric Yang-Mills theory is presented. It is found that in no case do both the leading terms in the

A theoretical framework to compute low-energy processes in a spontaneously broken gauge theory is devised. It applies in any gauge and uses conventional renormalisation schemes. Application of the
Regularization by dimensional reduction of supersymmetric and non-supersymmetric gauge theories
We apply the technique of dimensional reduction to both supersymmetric and non-supersymmetric theories. Explicit one- and two-loop calculations show that in the latter case the technique is a viable
