Maria Dimou09/07/2014 18:00This work aims to explain the masses and mixings of the fermionic content in the Standard Model and its supersymmetric extention, using a Family symmetry, in an SU(5)xS_4xU(1) GUT model. Results icorporate the GST and GS relations for quark and lepton masses and predict Tribimaximal mixing in the neutrino sector, corrected by a higher order operator. The goal is to predict flavvour changing...Go to contribution page

Adrien Hourlier09/07/2014 18:00Atmospheric muons represent an important background for neutrino oscillation experiments such as Double Chooz. They can cross the detector, depositing a great amount of energy, or decay after a few centimeters, depositing just enough energy to be miscounted as a neutrino interaction, or even trigger in the surrounding rock a shower of fast neutrons that can interact in the detector, mimicking...Go to contribution page

Jesus Alberto Acosta Lopez09/07/2014 18:00A model independent analysis of the leptonic Dirac CP‐violating phase ({\delta}) is presented. The analysis uses the experimentally determined values of the mixing angles in the lepton mixing matrix in order to explore the allowed values for {\delta} and possible general forms for the charged lepton mixing matrix. This is done under two general assumptions: 1) that the mixing matrix in the...Go to contribution page

Ivan Girardi09/07/2014 18:00We analyse the interplay of generalised CP transformations and the non‐Abelian discrete group T′ and use the semi‐direct product Gf=T′⋊HCP, as family symmetry acting in the lepton sector. The family symmetry is shown to be spontaneously broken in a geometrical manner. In the resulting flavour model, naturally small Majorana neutrino masses for the light active neutrinos are obtained through...Go to contribution page

Pedro Machado, Sara Saa Espina09/07/2014 18:00We deal here with the off‐shell renormalization of the chiral effective Lagrangian for physics beyond the Standard Model, based on a non‐linear realization of the $SU(2)_L\times U(1)_Y$ gauge symmetry breaking in the presence of a light Higgs particle, up to four derivatives. We consider the full would‐be Goldstone bosons and Higgs sector of the Lagrangian. All one loop amplitudes are computed...Go to contribution page

David Marzocca, Maria Cerda Sevilla09/07/2014 18:00After the successful determination of the reactor neutrino mixing angle \mbox{$\theta_{13} \cong 0.16 \neq 0$}, a new feature suggested by the current neutrino oscillation data is a sizeable deviation of the atmospheric neutrino mixing angle $\theta_{23}$ from $\pi/4$. Using the fact that the neutrino mixing matrix $U = U^\dagger_{e}U_{\nu}$, where $U_{e}$ and $U_{\nu}$ result from the...Go to contribution page

Zahra KHAJEH TABRIZI09/07/2014 18:00We study the highest energy sample of atmospheric neutrinos in the IceCube neutrino observatory to study for the first time the phenomenology of the matter effects of Large Extra Dimension Models. The oscillation probability in matter were computed for the LED model an distinct series of dips appear in anti‐ muon survival probability. We show that an effective 3+3*N model, which N is the...Go to contribution page
