  1. 19. Seaching for heavy sterile neutrinos in kaon decay
    Dr Cedric Weiland (IPPP Durham)
    24/03/2017 17:00
    Theory
    Ordinary
    The discovery of neutrino oscillations calls for an extension of the Standard Model that would generate neutrino masses and mixing. One of the simplest possibilities is the addition of fermionic gauge singlets or sterile neutrinos. Many experimental strategies have been proposed to search for heavy sterile neutrinos, depending on their mass. If their mass fall within the MeV-GeV range, they...

  2. 103. Recent results from IceCube on neutrino oscillations
    Joao Pedro Athayde Marcondes de Andre (Michigan State University)

    Experiment
    Ordinary
    The IceCube Neutrino Observatory, located at the South Pole, is the world's largest neutrino detector. IceCube is well placed to probe the existence of sterile neutrinos of around 1 eV², which is a region of particularly interest for the various anomalies motivating the existence of sterile neutrinos, by looking for resonant-enhanced muon neutrino disappearance around 1 TeV. In addition...

  3. 7. Search for sterile neutrinos at the DANSS and Neutrino-4 experiments
    Prof. Mikhail Danilov (NRNU MEPhI and LPI (Moscow))
    24/03/2017 17:40
    Experiment
    Ordinary
    DANSS is a one cubic meter highly segmented solid scintillator detector. It consists of 2500 scintillator strips (100x4x1 cm3), covered with gadolinium loaded reflective paint and read out by SiPMs via wave length shifting fibers. Groups of 50 strips are also read out by conventional PMT. DANSS is placed under a 3 GW reactor at the Kalinin NPP (Russia) on a movable platform. The distance...

  4. 59. Oscillations Beyond Three-Neutrino Mixing
    Dr Carlo Giunti (INFN)
    24/03/2017 18:00
    Theory
    Ordinary
    I review the experimental indications in favor of short-baseline neutrino oscillations. I discuss their interpretation in the framework of neutrino mixing schemes with one or more sterile neutrinos which have masses around the eV scale. I present arguments in favor of effective 3+1 neutrino mixing with one sterile neutrino at the eV scale. I present the results of the updated 3+1 global fit...

  5. 49. Latest results from the Pierre Auger Observatory
    Mlle Roberta Colalillo (INFN Napoli)
    24/03/2017 18:40
    Experiment
    Ordinary
    The Pierre Auger Observatory, located near Malargue, Argentina, is the world largest Ultra High Energy Cosmic Ray Observatory. It has been operating since 2004 and its exposure reached almost 60 000 km2 sr yr, providing an unprecedented large and high quality data set that have dramatically advanced our understanding of ultra-high energy cosmic rays. The suppression of the flux around...

  6. 22. New limits on neutrino magnetic moments
    Dr Omar Miranda (Cinvestav)
    24/03/2017 19:00
    Theory
    Ordinary
    An overview of the current bounds on neutrino magnetic moments will be given. The reactor, accelerator, and solar neutrino data will be used to obtain these constraints, and the interplay of these experiments will be remarked, especially in the case of the leptonic CP phases. The improvement of these limits in future experimental proposals will also be briefly discussed.
