      The cover page shows snapshots of a decaying Schrödinger cat Wigner function. This is a quasi-probability distribution for the amplitude of a microwave field stored in an ultra-high quality superconducting cavity. A single circular Rydberg atom interacting with a coherent state produces a quantum superposition of two fields with different phases. The two positive peaks in the Wigner function (front) are centered on the classical amplitudes of these components. The interference pattern in-between indicates the quantum nature of the superposition. As time proceeds (from front to rear), the interference pattern vanishes, revealing the rapid decoherence of a mesoscopic quantum state superposition.

    1. Status of three-neutrino oscillation parameters (pages 427–440)

      M. Tórtola

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200106

      The current status of global fits to neutrino oscillation data within the three-flavour framework is reviewed. The analysis includes the most recent data from solar and atmospheric neutrino experiments as well as the latest results from the long-baseline accelerator neutrino experiments and the recent measurements of reactor neutrino disappearance.

    2. Non-Abelian discrete symmetry for flavors (pages 441–465)

      H. Ishimori, T. Kobayashi, Y. Shimizu, H. Ohki, H. Okada and M. Tanimoto

      Version of Record online: 5 NOV 2012 | DOI: 10.1002/prop.201200124

      A short mathematical review on non-Abelian discrete groups that could be used as reference introduction to the actual flavor models proposed to account for the observed flavor structure of quarks and leptons is given. For the practical purpose of flavor model building, we present group-theoretical aspects of S3, S4, A4, D4, Δ(27) and Δ(54).

    3. Neutrino masses and mixing: a flavour symmetry roadmap (pages 466–492)

      S. Morisi and J.W.F. Valle

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200125

      Over the last ten years tri-bimaximal mixing has played an important role in modeling the flavour problem. Here is a short review of the status of flavour symmetry models of neutrino mixing. The authors concentrate on non-Abelian discrete symmetries, which provide a simple way to account for the TBM pattern.

    4. Origin of family symmetries (pages 493–506)

      H.P. Nilles, M. Ratz and P.K.S. Vaudrevange

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200120

      Discrete (family) symmetries might play an important role in models of elementary particle physics. The origin of such symmetries in the framework of consistent ultraviolet completions of the standard model in field and string theory is discussed.

    5. Tri-bimaximal neutrino mixing and discrete flavour symmetries (pages 507–534)

      G. Altarelli, F. Feruglio and L. Merlo

      Version of Record online: 5 NOV 2012 | DOI: 10.1002/prop.201200117

      he application of non-Abelian discrete groups to Tri-Bimaximal (TB) neutrino mixing, which is supported by experiment as a possible good first approximation to the data is reviewed. The virtues and the problems of TB mixing models are discussed, also in connection with lepton flavour violating processes, and the different approaches are compared.

    6. μ–τ interchange symmetry and lepton mixing (pages 535–545)

      W. Grimus and L. Lavoura

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200118

      Focusing on the use of a μ–τ interchange symmetry the features of lepton mixing, especially maximal atmospheric neutrino mixing are explained. The symmetry may be embedded in a generalized CP symmetry. Arguments of naturalness are used for explaining the smallness of the mass ratio mμ / mτ.

    7. The S3 flavour symmetry: Neutrino masses and mixings (pages 546–570)

      F. González Canales, A. Mondragón and M. Mondragón

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200121

      The article offers explanations for the neutrino masses and mixings as the realization of an S3 flavour permutational symmetry in two models, namely the Standard Model and its extension with three Higgs bosons. Both cases the numerical values of the neutrino mixing angles can be obtained in excellent agreement with experimental data by choosing masses in a suitable way.

    8. Neutrino mixings and the S4 discrete flavour symmetry (pages 571–596)

      F. Bazzocchi and L. Merlo

      Version of Record online: 5 NOV 2012 | DOI: 10.1002/prop.201200123

      The main application of the S4 discrete group as a flavour symmetry are reviewed, first dealing with the formalism and later with the phenomenological implications. In particular, the main features of flavour models based on S4 are discussed.

    9. Super flavorsymmetry with multiple Higgs doublets (pages 597–621)

      J. Kubo

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200119

      If spontaneous CP violation is combined with non-Abelian super flavorsymmetry the CP phases in the soft supersymmetry breaking sector can disappear. This feature of super flavorsymmetry is reviewed and elaborated in a supersymmetric model of flavor based on the finite group Q6. The predictions of the model in fermion mass and mixing, and flavor and CP violation can be tested in future experiments.

    10. Lepton flavour violation and flavour symmetries (pages 622–644)

      F.F. Deppisch

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200126

      In this review article, the impact of models incorporating flavour symmetries on charged lepton flavour violating (LFV) processes is illustrated. Flavour symmetries provide a natural approach to explain the peculiar mass hierarchies and mixing patterns of the Standard Model fermions. The focus is set on searches for low-energy LFV processes such as μ [RIGHTWARDS ARROW] e γ or μ-e conversion in nuclei but also on the potential impact of LFV processes at the LHC.

    11. The role of lepton flavor symmetries in leptogenesis (pages 645–665)

      D. Aristizabal Sierra and I. de Medeiros Varzielas

      Version of Record online: 11 OCT 2012 | DOI: 10.1002/prop.201200122

      The presence of flavor symmetries in the lepton sector may have several consequences. The mechanism in general type-I, type-II and type-III seesaw models and consequences for the generation of the baryon asymmetry of the Universe via leptogenesis are reviewed.
