In the context of a simple yet realistic description of quark masses and mixings given by a certain class of mass matrices, we study the robustness of a hierarchical model with respect to arbitrary random perturbations in phases and magnitudes of the matrix elements. We call these random perturbations anarchy. We determine the level of fluctuations that arise in physical observables such as the...

The consequences of adding random perturbations (anarchy) to a baseline hierarchical model of quark masses and mixings are explored. Even small perturbations of the order of 5% of the smallest non-zero element can already give deviations significantly affecting parameters of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, so any process generating the anarchy should in general be limited to this or...

متن کاملAnarchy and Hierarchy *
We advocate a new approach to study models of fermion masses and mixings, namely anarchy proposed in Ref. [1]. In this approach, we scan the O(1) coefficients randomly. We argue that this is the correct approach when the fundamental theory is sufficiently complicated. Assuming there is no physical distinction among three generations of neutrinos, the probability distributions in MNS mixing angl...
متن کاملModels of Neutrino Masses: Anarchy versus Hierarchy
We present a quantitative study of the ability of models with different levels of hierarchy to reproduce the solar neutrino solutions, in particular the LA solution. As a flexible testing ground we consider models based on SU(5)×U(1)F. In this context, we have made statistical simulations of models with different patterns from anarchy to various types of hierachy: normal hierarchical models wit...
