Dr Henso Abreu (Israel Institute of Technology (IL))06/10/2015, 10:30Astroparticle PhysicsOral PresentationSearches for strongly produced dark matters in events with jets, photons, heavy-flavor quarks or massive gauge bosons recoiling against large missing transverse momentum in ATLAS are presented. These “MET+X” signatures provide powerful probes to dark matter production at the LHC, allowing us to interpret results in terms of effective field theory and/or simplified models with pair...Go to contribution page

Prof. Mario Bertaina (University of Torino and INFN Torino)06/10/2015, 10:50Astroparticle PhysicsOral PresentationCosmic Rays above 10^17 eV allow studying hadronic interactions at energies that can not be attained at accelerators yet. At the same time hadronic interaction models have to be applied to the cosmic-ray induced air-shower cascades in atmosphere to infer the nature of cosmic rays. The reliability of air-shower simulations has become the source of one of the largest systematic uncertainty in...Go to contribution page

Ralf Ulrich (KIT)06/10/2015, 11:15Astroparticle PhysicsOral PresentationMany LHC measurements have already been used to improve hadronic interaction models and thus lowered the model dependence of cosmic ray data analyses. However, the LHC still has a lot more potential to provide crucial information, which has not been fully exploited so far. Since the start of Run2 the highest accelerator beam energies are reached and no further increase can be expected for a...Go to contribution page

Dr Sergey Ostapchenko (Frankfurt Institute for Advanced Studies (FIAS))06/10/2015, 11:40Astroparticle PhysicsOral PresentationI shall review the state-of-the-art concerning the treatment of high energy cosmic ray interactions in the atmosphere, discussing in some detail the underlying physical concepts and presenting a comparison of model results with selected accelerator data. Further, the relation of basic characteristics of hadronic interactions with the properties of nuclear-electromagnetic cascades induced by...Go to contribution page

Dr Darko Veberic (Institute for Nuclear Physics, Karlsruhe Institute of Technology)06/10/2015, 12:35Astroparticle PhysicsOral PresentationThe muon content of extensive air showers produced by the ultra-high energy cosmic rays is an observable sensitive to the composition of the primary particle and to the properties of hadronic interactions driving the air-shower cascade. We present different methods to estimate the muon number at the ground and the muon production depth using measurements of the longitudinal, lateral, and...Go to contribution page

Dr Rasha Abbasi (University of Utah)06/10/2015, 12:55Astroparticle PhysicsOral PresentationDetecting Ultra High Energies Cosmic Rays (UHECRs) enables us to measure the proton-air inelastic cross section $\sigma^{\rm inel}_{\rm p-air}$ at energies that we are unable to access with particle accelerators. The proton-proton cross section $\sigma_{\rm p-p}$ is subsequently inferred from the proton-air cross section at these energies. UHECRs experiments have been reporting on the...Go to contribution page

Prof. Elisa Resconi (TU Munchen)06/10/2015, 13:15Astroparticle PhysicsOral PresentationThe neutrino observatory IceCube is opening a new observational window to the Universe. IceCube, which has been constructed in the icecap at the South Pole, is taking data since Spring 2011 in full configuration. The first years of data reveled the existence of extremely high neutrinos at the PeV scale. The observed diffuse neutrino flux is with high probability of astrophysical origin....Go to contribution page

Dr Gwenael Giacinti (MPIK, Heidelberg)06/10/2015, 13:35Astroparticle PhysicsOral PresentationIceCube telescope has detected ~TeV-PeV neutrinos of astrophysical origin. Currently, their origin is still unknown. In this talk, we will review the main recent theoretical explanations for these high-energy neutrinos. Both scenarios of a Galactic origin (such as the Fermi bubbles, cosmic rays in the halo, or other Galactic sources) and of an extragalactic origin (such as active galactic...Go to contribution page
