Château de Button
Description
The "Invisibles School 14" precedes the third thematic workshop organised in the context of the FP7 funded INVISIBLES ITN (FP7-PEOPLE-2011-ITN, PITN-GA-2011-289442-INVISIBLES), which focuses on Neutrino, Dark Matter and Dark Energy phenomenology and their connection, and more in general on physics beyond the Standard Model of Particle Physics.


The School will take place in the beautiful "Château de Button", in Gif-Sur-Yvette (25 kms from Paris), and will be followed by the Invisibles 2014 Workshop, held at the "Institut des Cordeliers" in the centre of Paris (6th "arrondissement").

This year's edition of the Invisibles School will focus on several aspects of neutrino physics.

        An SU(5)xS4xU(1) supersymmetric model of flavor 1h
        This 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 processes, relevant for lepton flavour violation and B‐physics experiments. Based on work done with M. Dimou, S. F. King, C. Luhn, C. Hagedorn

        Atmospheric muon-induced background study for the Double Chooz experiment 1h
        Atmospheric 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 a neutrino signal. Although solutions exist to veto out crossing muons with a near 4π coverage, the geometry of Double Chooz detectors allow some muons to decay into the active detection volume. I will present a study aiming to reduce this background based on the likelihood of the event reconstruction algorithm. I will also present DCTPC, a neutron TPC developed to provide a directional measurement of the fast neutron flux in Double Chooz detector halls. This measurement will allow us to further constrain Double Chooz’s model of fast neutron background. Based on work done with Adrien Hourlier, Jaime Dawson

        CP violating phase from charged-lepton mixing 1h
        A 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 neutrino sector is the so‐called tribimaximal matrix and hence the non zero value for {\theta}13 arises due to the mixing matrix in the charged lepton sector and 2) the charged lepton mixing matrix is parametrized in terms of three angles and one phase. It is found that any value of {\delta} is still consistent with the data and that, considering the assumptions above, regardless of the value for {\delta}, the 1‐3 mixing angle in the charged lepton sector is small but non zero and the 2‐3 mixing angle can take values in only two possible small ranges around 0 and {\pi}/2 respectively.

        Generalised geometrical CP violation in a T' lepton flavour model 1h
        We 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 the type I see‐saw mechanism. The known masses of the charged leptons, lepton mixing angles and the two neutrino mass squared differences are reproduced by the model with a good accuracy. The model allows for two neutrino mass spectra with normal ordering (NO) and one with inverted ordering (IO). For each of the three spectra the absolute scale of neutrino masses is predicted with relatively small uncertainty. The value of the Dirac CP violation (CPV) phase δ in the lepton mixing matrix is predicted to be δ≅π/2 or 3π/2. Thus, the CP violating effects in neutrino oscillations are predicted to be maximal (given the values of the neutrino mixing angles) and experimentally observable. We present also predictions for the sum of the neutrino masses, for the Majorana CPV phases and for the effective Majorana mass in neutrinoless double beta decay. The predictions of the model can be tested in a variety of ongoing and future planned neutrino experiments. Based on work done with I. Girardi, A. Meroni, S. T. Petcov and M.

        On the renormalization of the electroweak chiral Lagrangian 1h
        We 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 using dimensional regularization. Apparent chiral noninvariant divergences are encountered in the process. Nevertheless, they are non‐physical. We provide a method for the renormalization of these amplitudes off‐ shell, which involves a redefinition of the would‐be Goldstone boson fields that includes space‐time derivatives and the Higgs field.

        Predicting the neutrino CP phase with charged lepton corrections 1h
        After 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 diagonalisation of the charged lepton and neutrino mass matrices, and assuming that $U_{\nu}$ has a i) bimaximal (BM), ii) tri‐ bimaximal (TBM) form, or else iii) corresponds to the conservation of the lepton charge $L' = L_e ‐ L_\mu ‐ L_{\tau}$ (LC), we investigate quantitatively what are the minimal forms of $U_e$, in terms of angles and phases it contains, that can provide the requisite corrections to $U_{\nu}$ so that $\theta_{13}$, $\theta_{23}$ and the solar neutrino mixing angle $\theta_{12}$ have values compatible with the current data. Two possible orderings of the 12 and the 23 rotations in $U_e$, ``standard'' and ``inverse'', are considered. The results we obtain depend strongly on the type of ordering. In the case of ``standard'' ordering, in particular, the Dirac CP violation phase $\delta$, present in $U$, is predicted to have a value in a narrow interval around i) $\delta \cong \pi$ in the BM (or LC) case, ii) $\delta \cong 3\pi/2$ or $\pi/2$ in the TBM case, the CP conserving values $\delta = 0, \pi, 2\pi$ being excluded in the TBM case at more than $4\sigma$.

        Probing large extra dimensions with IceCube 1h
        We 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 number of sterile states that can effectively reproduce and explain these dips. From the absence of the observed oscillation in the high energy data of IceCube we can constrain the radius of the large extra dimension R_ED < 6 × 10^−5 cm and m^D_1 < 2.7 eV for IceCube‐40 data and R_ED < 3.5 × 10^−5 cm and m^D_1 < 4.0 eV for IceCube‐79 data.
