    The GERDA collaboration is performing a sensitive search for neutrinoless double beta decay of $^{76}$Ge at the INFN Laboratori Nazionali del Gran Sasso, Italy. The upgrade of the GERDA experiment from Phase I to Phase II has been concluded in December 2015. The first P...

    The observed pattern of mixing in the neutrino sector may be explained by the presence of a non-Abelian, discrete flavour symmetry broken into residual subgroups at low energies. Many flavour models require the presence of Standard Model singlet scalars which can prompt...

    We discuss the breaking of $SO(3)$ down to finite family symmetries such as $A_4$, $S_4$ and $A_5$ using supersymmetric potentials for the first time. We analyse in detail the case of supersymmetric $A_4$ and its finite subgroups $Z_3$ and $Z_2$. We then propose a super...

    Project: RCUK | Exploring the limits of t... (ST/L000296/1), EC | ELUSIVES (674896), EC | InvisiblesPlus (690575)

    We propose supersymmetric Majoron inflation in which the Majoron field $\Phi$ responsible for generating right-handed neutrino masses may also be suitable for giving low scale "hilltop" inflation, with a discrete lepton number $Z_N$ spontaneously broken at the end of in...

    Neutrino masses and their ordering: Global Data, Priors and Models
    Open Access English
    Authors:
    P. F. de Salas; M. Tórtola; Olga Mena; S. Gariazzo; C.A. Ternes; Maria Archidiacono;
    doi: 10.1088/1475-7516/2018/03/011
    Project: EC | ELUSIVES (674896), EC | InvisiblesPlus (690575)

    We present a Bayesian analysis of the combination of current neutrino oscillation, neutrinoless double beta decay and CMB observations. Our major goal is to carefully investigate the possibility to single out one neutrino mass ordering, Normal Ordering or Inverted Order...

    Flavourful Z ' models for {R}_{K^{(\ast )}}

    Project: RCUK | Exploring the limits of t... (ST/L000296/1), EC | ELUSIVES (674896), EC | InvisiblesPlus (690575)

    We show how any flavour conserving $Z'$ model can be made flavour violating and non-universal by introducing mass mixing of quarks and leptons with a fourth family of vector-like fermions with non-universal $Z'$ couplings. After developing a general formalism, we focus ...
