Quark 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 کاملQuark Mass Matrices in Orbifold Models
We study left-right symmetric quark mass matrices whose upand down-sectors have the same structure. This type of realistic mass matrices are derived from orbifold models. Alexander von Humboldt Fellow e-mail: [email protected] The origin of the fermion masses is one of the most important problems in particle physics. Higher dimension couplings could explain the hier...
متن کاملTop Quark Mass Prediction in Superstring Derived Standard–like Models
A remarkable achievement of the realistic superstring standard–like models is the successful prediction of the top quark mass, assuming the Minimal Supersymmetric Standard Model spectrum below the string scale. Recently it was shown that string scale unification requires the existence of additional matter, in vector–like representations, at intermediate energy scales and that certain string mod...
متن کاملDynamical Mass Matrices from Effective Superstring Theories
We analyze the general structure of the fermion mass matrices in effective superstrings. They are generically given at low energy by non-trivial functions of the gauge singlet moduli fields. Interesting structures appear in particular if they are homogeneous functions of zero degree in the moduli. In this case we find Yukawa matrices very similar to the ones obtained by imposing a U(1) family s...
متن کاملLepton and Quark Mass Matrices
We propose a model that all quark and lepton mass matrices have the same zero texture. Namely their (1,1), (1,3) and (3,1) components are zeros. The mass matrices are classified into two types I and II. Type I is consistent with the experimental data in quark sector. For lepton sector, if seesaw mechanism is not used, Type II allows a large νμ-ντ mixing angle. However, severe compatibility with...
