From Superstring Derived Models
It was recently suggested that the reported anomalies in Rb and Rc can be interpreted as the effect of a heavy vector boson that couples to quarks and is universally decoupled from leptons. We examine how an extra gauge boson with this property can arise from superstring derived models. In a specific three generation model we show that the U(1)B−L symmetry combines with the horizontal flavor sy...
متن کاملQuark Mass Matrices in Superstring Models
Four simple but realistic patterns of quark mass matrices are derived from orbifold models of superstring theory in the absence of gauge symmetries. Two of them correspond to the Ramond-Roberts-Ross types, which have five texture zeros in up and down quark sectors. The other two, with four texture zeros, preserve the structural parallelism between up and down sectors. The phenomenological conse...
متن کاملExact superstring motivated cosmological models Richard
We present a number of new, exact scalar field cosmologies where the potential consists of two or more exponential terms. Such potentials are motivated by supergravity or superstring models formulated in higher dimensional spacetimes that have been compactified to (3+1)-dimensions. We have found solutions in both curved and flat Robertson Walker spacetimes. These models have a diverse range of ...
متن کاملGeneration Mass Hierarchy in Superstring Derived Models
I discuss the problem of generation mass hierarchy in the context of realistic superstring models which are constructed in the free fermionic formulation. These models correspond to models which are compactified on Z2 × Z2 orbifold. I suggest that the hierarchy among the generations results from horizontal symmetries, which arise from the compactification. In particular, I show that in a class ...
متن کاملConstruction of Realistic superstring Standard-like Models.
I discuss the construction of realistic superstring standard–like models in the four dimensional free fermionic formulation. I discuss proton lifetime constraints on superstring models. I discuss the massless spectrum of the superstring standard–like models, the texture of fermion mass matrices in these models and argue that the realistic features of these models are due to the underlying Z2 × ...
