  1. 56. Determination of atmospheric neutrino mixing parameters and octant of θ23 at INO-ICAL detector
    Mlle Daljeet Kaur (University of Delhi)
    16/03/2015 19:30
    Experiment
    YSF (Young Scientists Forum)
    The India-based Neutrino Observatory (INO) is an approved atmospheric neutrino project, located at Theni (TamilNadu) in South India. A 50 kt magnetized Iron CALorimeter (ICAL) detector will be the main detector at INO for the determination of correct neutrino mass ordering, right octant of mixing angle θ23 and also for precise measurement of current mixing parameters. The detector will have...

  2. 30. EDELWEISS III
    M. Thibault de Boissière (CEA)
    16/03/2015 19:37
    Experiment
    YSF (Young Scientists Forum)
    EDELWEISS is a dark matter direct-detection experiment, currently in its third phase. It operates cryogenic Germanium bolometers in the Underground Laboratory of Modane. A specific design of heat sensors and interleaved electrodes is used to efficiently reject background events. We present the status and performance of the ongoing physics run, in particular in view of low mass wimp searches.

  3. 11. Making sense of the local Galactic escape speed estimates in direct dark matter searches

    Theory
    YSF (Young Scientists Forum)
    The knowledge of the high velocity tail of the WIMP velocity distribution function has a strong impact on the way direct detection (DD) may constrain or discover light WIMPs in the GeV mass range. Recently, there have been important observational efforts to estimate the so-called Galactic escape speed at the position of the Earth, like for instance the analysis published in early 2014 by...

  4. 29. Search for a sterile neutrino with the STEREO detector at ILL.
    M. Stephane Zsoldos (LPSC)
    16/03/2015 19:51
    Experiment
    YSF (Young Scientists Forum)
    In 2011, a re-evaluation of the anti-neutrino spectrum emitted by nuclear reactors revealed a 6% deficit between the observed flux and the expected one. This anomaly is significant at 2.7sigmas and can be explain by a new oscillation at short range due to a light sterile neutrino, with parameter Δm² = 0.1-1 eV. The STEREO detector in construction at ILL will be the first ever to measure with...

  5. 34. WIMP Annihilations in the Sun : A search using first year of operation of the completed IceCube neutrino telescope.
    M. MOHAMED RAMEEZ (University of Geneva)
    16/03/2015 19:58
    Experiment
    YSF (Young Scientists Forum)
    Weakly Interacting Massive Particles, which are possible candidates for Dark Matter can be gravitationally captured in the Sun and undergo self annihilation to produce standard model particles including neutrinos. The resulting neutrino flux from the Sun could be detected by terrestrial neutrino telescopes such as IceCube. In addition to the standard analysis using upward going neutrino...

  6. 10. NEMO-3 Analysis of the double-$\beta$ decay of 96Zr
    M. Guillaume Eurin (LAL, Orsay, France / UCL, London, UK)
    16/03/2015 20:05
    Experiment
    YSF (Young Scientists Forum)
    The NEMO-3 detector was operated from 2003 to 2010 in the underground laboratory of Modane. Its main goal was the search for neutrinoless double-$\beta$ decay. Its discovery would prove that neutrinos are Majorana particles, meaning that the neutrino is its own antiparticle. This could help explaining the origin of the neutrino mass. The current best lower limits on the half-lives of this...

  7. 22. Radiative neutrino masses and dark matter
    M. David R. Lamprea (Institut für Theoretische Physik, Universität Münster)
    16/03/2015 20:12
    Theory
    YSF (Young Scientists Forum)
    The Standard Model, despite its tremendous theoretical and experimental success, is known to lack explanation for several physical realities, namely gravity, dark energy, dark matter, and the neutrino masses. Of these, the last two are arguably related to the electroweak sector. Neutrino masses can be generated by different realizations of the Weinberg operator. In particular, radiative...
