Dr Valentina De Romeri (CNRS)16/03/2015 08:30TheoryOrdinaryA future high-luminosity Z-factory will offer the possibility to study rare Z decays, as those leading to lepton flavour violating final states. Processes such as Z → l∓1 l±2 are potentially complementary to low-energy (high-intensity) observables of lepton flavour violation. We address the impact of new sterile fermions on lepton flavour violating Z decays, focusing on potential searches at...Go to contribution page

M. Juan Pablo Yanez (DESY)16/03/2015 08:50ExperimentOrdinaryThe IceCube Neutrino Observatory is a cubic kilometer ice Cherenkov neutrino detector, located at the geographic South Pole, detecting neutrinos starting at energies of about 10 GeV. In the last couple of years IceCube has established the existence of a high-energy astrophysical neutrino flux in the 100 TeV - PeV range at the level of $10^{-8}$ GeV cm$^{-2}$ s$^{-1}$ sr$^{-1}$ per flavor with...Go to contribution page

Dr Aaron Vincent (IPPP Durham)16/03/2015 09:15TheoryOrdinaryThe recent detection of 37 high-energy neutrinos of astrophysical by the IceCube experiment at the South Pole has signalled the beginning of high-energy neutrino astronomy. At these energies, neutrinos are expected to be produced by pion disintegration after production in high-energy sources. This should lead to a democratic flavour composition at Earth of (1:1:1) electron : muon : tau...Go to contribution page

Dr Manuel Masip (Universidad de Granada)16/03/2015 09:35TheoryOrdinaryIceCube has recently published the observation of 37 events of TeV-PeV energies. It is apparent that their angular distribution, spectrum and muon to shower ratio can not be explained assuming standard interactions of atmospheric neutrinos. We obtain an excellent fit, however, if a diffuse flux of ultrahigh energy (cosmogenic) neutrinos experiences collisions where only a small fraction of the...Go to contribution page

Dr Gianmarco Bruno (Muenster University)16/03/2015 10:20ExperimentOrdinaryThe XENON100 experiment, located at the Laboratori Nazionali del Gran Sasso (LNGS), reached sensitivities on the WIMP-nucleon spin-independent cross section down to 2×10 −47 cm 2 after two years of data taking, excluding the signal at 90 % C.L. Other analysis, in different theoretical framework, have been also published. The next generation experiment, XENON1T, is currently in the...Go to contribution page

Mlle Caterina Doglioni (University of Oxford)16/03/2015 10:40ExperimentOrdinaryDespite the recent discovery of the Higgs boson contributing to the success of the Standard Model, the large excess of Dark Matter in the universe remains one of the outstanding questions in science. This excess cannot be explained by Standard Model particles; a compelling hypothesis is that Dark Matter is comprised of particles can be produced at the LHC, called Weakly Interacting Massive...Go to contribution page

Dr Giorgio Arcadi (LPT Orsay)16/03/2015 11:25TheoryOrdinaryWe discuss the possibility of reproducing the recently reported 3:55 KeV line in some simple decaying dark matter scenarios. The decaying Dark Matter is coupled to the Standard Model(SM) through a scalar field charged under the SM group which can pair produced at the LHC. The DM density is generated through freeze-in by the decay of the scalar field. The combined constraints from DM Inderect...Go to contribution page

Jochen Schieck (Institute of High Energy Physics)16/03/2015 17:00ExperimentOrdinaryThe quest for the particle nature of Dark Matter is one of the big open questions of modern physics. The CRESST II experiment located at the Gran Sasso laboratory in Italy is optimised for the detection of the elastic scattering of Dark Matter particles with ordinary matter. We present the result obtained with an improved detector setup with increased radio purity and enhanced background...Go to contribution page

Dr Davide Franco (APC)16/03/2015 17:20ExperimentOrdinaryDarkSide-50 is dual-phase liquid argon time projection chamber, designed for direct WIMP search. The detector, consisting of 50 kg of liquid argon and shielded by active neutron and muon vetoes, is installed at Gran Sasso underground laboratory. DarkSide-50 is taking data since November 2013, collecting more than 10^7 events with atmospheric argon, naturally contaminated with cosmogenic 39Ar...Go to contribution page

Dr Ninetta Saviano (IPPP, Durham University)16/03/2015 17:40TheoryOrdinaryLight sterile neutrinos (eV scale), suggested by different anomalies observed in short-baseline neutrino oscillation experiments, can be produced in the early universe by oscillations with the active neutrinos and can affect different cosmological observables: Big Bang Nucleosynthesis (BBN), Cosmic Microwave Background (CMB) and Structure Formation (LSS). Indeed, if the sterile neutrinos...Go to contribution page

Dr Julien Billard (IPNL)16/03/2015 18:00ExperimentOrdinaryDark matter detectors are rapidly improving in sensitivity, and as they continue to increase in size and reduce thresholds, they will encounter the neutrino background, at which point Solar, atmospheric, and diffuse supernova neutrinos will interfere with a potential dark matter signal. Neutrino interactions in these detectors will occur through both coherent neutrino-nucleus scattering (CNS)...Go to contribution page
