Benjamin Jones (MIT), Benjamin Jones (H. H. Wills Physics Laboratory-University of Bristol-Unknown)05/05/2015, 14:00parallel talkThis talk will cover progress towards understanding the coherence properties of neutrino beams, using an open-quantum-systems approach to neutrino production. A new derivation of the generalized neutrino oscillation probability from arbitrarily prepared pions will be presented, followed by a calculation of the pion state that evolves through electromagnetic interactions with decay pipe gases....Go to contribution page

Mr Guang Yang (Argonne/IIT)05/05/2015, 14:15parallel talkPrecise measurement of the neutrino mixing angle theta13 is the primary goal of the Double Chooz Experiment. Inverse beta decay process provides a unique signature of anti-neutrino interaction from the reactors, giving prompt signals from positron annihilation and delayed signals from neutron capture by either Gadolinium (Gd) or Hydrogen (H). In this talk, the latest Gd- and H-based...Go to contribution page

Dr David Vanegas Forero (Center for Neutrino Physics, Virginia Tech)05/05/2015, 14:30parallel talkIn this talk the three neutrino framework that describes the standard neutrino oscillations will be briefly introduced enphasizing on the role of the Daya Bay reactor neutrino experiment. After the introduction, the Daya Bay power to constraint charge current non-standard neutrino interactions (NSI) will be presented. The impact of the systematical error in the total normalization of the...Go to contribution page

Dr Yong Tang (KIAS)05/05/2015, 14:45parallel talkWe propose a mechanism to reconcile eV sterile Neutrinos, suggested by short baseline experiments, with cosmological mass bounds. New self-interactions are neccessarily introduced for sterile neutrinos to suppress their production in the early Universe.Go to contribution page

Ayuki Kamada (University of California, Riverside)05/05/2015, 15:00parallel talkRecently IceCube experiment has revealed the spectrum of cosmic neutrinos in TeV-PeV range. However, null detection of 400-800 TeV neutrinos disagrees with a power law energy spectrum implied by the others. We interpret this "dip" feature as a hint of neutrino self-interactions. We investigate the possibility that well-motivated U(1)Lmu-Ltau model can explain the feature. We show that future...Go to contribution page

Trinh Le (University of Virginia)05/05/2015, 15:15parallel talkWe present a model of neutrino masses within the framework of the EW-$\nu_R$ model in which the experimentally desired form of the PMNS matrix is obtained by applying an $A_4$ symmetry to the *Higgs singlet sector* responsible for the neutrino Dirac mass matrix. This mechanism naturally avoids potential conflict with the LHC data which severely constrains the Higgs sector, in particular the...Go to contribution page

Mr Arindam Das (University of Alabama)05/05/2015, 15:30parallel talkWith the heavy Standard Model (SM) singlet neutrinos, the (inverse) seesaw mechanism provides us with a natural way to incorporate the neutrino mass in the SM. If the heavy neutrinos have their mass of the electroweak scale, they can be produced at the Large Hadron Collider (LHC) through their mixing with the SM light neutrinos. We investigate the heavy neutrino production processes at the...Go to contribution page

Bhupal Dev (University of Manchester)05/05/2015, 15:45parallel talkWe discuss the future prospects of heavy neutrino searches at future lepton colliders. In particular, we focus on the planned electron-positron colliders, operating in two different beam modes, namely, $e^+e^-$ and $e^-e^-$. In the $e^+e^-$ beam mode, we consider various production and decay modes of the heavy neutrino ($N$), and find that the final state with $e+2j+\not{\!E}$, arising from...Go to contribution page
