Quark Masses and Flat Directions in String Models
نویسنده
چکیده
I discuss a method for producing a quasi–realistic inter–generational quark mass hierarchy in string models. This approach involves non–Abelian singlet states developing intermediate scale vacuum expectation values. I summarize recent investigations into string model realization of this. Talk presented at QCD98, Paris, France, 1–6 June 1998.

Se p 19 98 Flat directions , String Compactification and 3 Generation Models
We show how identification of absolutely flat directions allows the construction of a new class of compactified string theories with reduced gauge symmetry that may or may not be continuously connected to the original theory. We use this technique to construct a class of 3 generation models with just the Standard Model gauge group after compactification. We discuss the low-energy symmetries nec...

In this paper, we have considered that the strange-star consists of quark matter from its center to surface. For quark matter, we have used two models, the MIT bag model and string-flip like model. In the bag model, the energy of the system has been considered the kinetic energy of the particles of system in addition to a constant B. We have considered two states for B, one of them is constant...
متن کاملCalculating Fermion masses in Superstring Derived Standard–like Models
One of the intriguing achievements of the superstring derived standard–like models in the free fermionic formulation is the possible explanation of the top quark mass hierarchy and the successful prediction of the top quark mass. An important property of the superstring derived standard–like models, which enhances their predictive power, is the existence of three and only three generations in t...
متن کاملPatterns of Quark Mass Matrices in a Class of Calabi - Yau Models
We study a class of superstring models compactified in the 3-generation Calabi-Yau manifold of Tian and Yau. Our analysis includes the complete E 6-singlet sector, which has been recently evaluated using techniques of spectral and exact sequences. We use the discrete symmetries of the models to find flat directions of symmetry breaking that leave unbroken a low energy matter parity and make all...
متن کاملGeneric Formula of Soft Scalar Masses in String Models
We derive formula of soft supersymmetry breaking scalar masses from 4-dimensional string models within a more generic framework. We consider effects of extra gauge symmetry breakings including an anomalous U(1) breaking through flat directions, that is, D-term and F -term contributions, particle mixing effects and heavy-light mass mixing effects. Some phenomenological implications are discussed...
