  1. 314. Renormalization Group Evolution of Neutrino Masses in Type I and Type II Seesaw Scenarios
    Mr Michael Schmidt (Max-Planck Institut für Kernphysik)

    Parallel Talk
    Analytical formulae of the renormalization group equations are presented in terms of mixing parameters for type I and type II seesaw models. The evolution of neutrino mass parameters are discussed in the SM extended by right-handed neutrinos and a Higgs triplet as well as the extended MSSM. Implications for testing predictions of mass models with future precision experiments are analyzed.

  2. 113. Constructing Seesaw Textures in Quark-Lepton Complementarity

    We systematically construct the seesaw textures compatible with current data from generic assumptions. We use the context of extended quark-lepton complementarity, i.e., we assume that all contributing mixing angles and mass hierarchies can be described by a small quantity of the order the Cabibbo angle as a single remnant of a Grand Unified Theory. We do not impose special assumptions,...

  3. 292. Can LHC Test the See-Saw Mechanism?

    Flavor Physics
    Parallel Talk
    We consider the prospects for detecting right-handed (Standard Model singlet) neutrinos introduced in the see-saw mechanism at future accelerators. This requires sufficiently large mixing of these neutrinos with the left-handed neutrinos, which is only possible if contributions from different right-handed neutrinos to the light neutrino mass matrix cancel at a level of $10^{-8}$. We...

  4. 150. Neutrino Masses and Mixings from Quark Mass Hierarchies

    Parallel Talk
    Motivated by SO(10) models with a vectorial fourth generation of down quarks and leptons, we consider the scenario where the neutrino Majorana and Dirac mass matrices conincide with those of up- and down-quarks, respectively. Then the small neutrino mass hierarchy follows from the mismatch of the quark mass hierarchies. Together with the observed leptonic mixing angles, we arrive at a...

  5. 205. SO(10) SUSY GUTs with family symmetries: the test of FCNCs
    Mr Wolfgang Altmannshofer (Technische Universität München)

    Flavor Physics
    Parallel Talk
    Flavor changing neutral current (FCNC) processes, being forbidden in the Standard Model at the tree level, play an important role in the test of extensions of this model. One popular class of new physics models are Grand Unified Theories (GUTs). Such models, when supplemented by flavor symmetries allow for concrete predictions for various observables - including FCNC processes - in terms...

  6. 207. Flavor violation in a SUSY GUT
    Dr Jae-hyeon Park (Tohoku University)

    Flavor Physics
    Parallel Talk
    Leptonic and hadronic flavor violations are studied in a general SU(5)-type supersymmetric grand unification model. Due to a GUT symmetry relating quarks and leptons, flavor violating processes in both sectors can be used to constrain a given single source of flavor non-universality at the GUT scale. Without assuming a very specific boundary condition on the soft supersymmetry breaking...
