GRAND UNIFICATION AT SLC/LEP
"... We present a general relationship between grand unification parameters and observables at the SLC and LBP e+e colliders. These include the 2 and W vector boson masses and, in particular, the polarization asymmetry ALR, a highly sensitive measure of the electroweak mixing sin2 8~. We show that ALR p ..."

1 Topological Grand Unification
, 810
"... We propose a new grand unification scenario to guarantee the proton stability and the tripletdoublet Higgs mass splitting with the help of a topological symmetry and a dynamics. The grand unification is an attractive idea and offers unification of forces and (partial) unification of quarks and lept ..."

Geometry of Grand Unification
"... Grand Unification of all forces has been a well motivated paradigm for particle physics. This subject has been recently revisited in the context of string theory, leading to a geometric reformulation of the idea of unification of forces. The interplay between geometry and physics has led to a natura ..."

Partly Supersymmetric Grand Unification
, 2004
"... 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 ..."

The Dirac Algebra and Grand Unification
, 2001
"... Abstract. A representation of the Dirac algebra, derived from first principles, can be related to the combinations of unit charges which determine particle structures. The algebraic structure derives from a broken symmetry between 4vectors and quaternions which can be applied to the broken symmetry ..."

symmetry between the three nongravitational interactions. The significance of this relation for Grand Unification is derived by explicit calculation of the running values of the fine structure constants, with suggestions for the calculation of particle masses. 1 The origin of the Dirac algebra Four
Grand Unification in String Theory
, 1996
"... We give a classification of 3family SO(10) and E6 grand unification in string theory within the framework of conformal field theory and asymmetric orbifolds. We argue that the construction of such models in heterotic string theory requires certain Z6 asymmetric orbifolds that include a Z3 outerauto ..."

Ftheory Grand Unification
, 811
"... In Ftheory GUT constructions Yukawa couplings necessarily take place at the intersection of three matter curves. For generic geometric configurations this gives rise to problematic Yukawa couplings unable to reproduce the observed hierarchies. We point out that if the U(1)B−L/U(1)Y flux breaking th ..."

Grand Unification in Higher Dimensions
"... We have recently proposed an alternative picture for the physics at the scale of gauge coupling unification, where the unified symmetry is realized in higher dimensions but is broken locally by a symmetry breaking defect. Gauge coupling unification, the quantum numbers of quarks and leptons and the ..."
