45. Detection techniques for neutrinos and high energy astrophysics

Flavio Gatti (GE)

22/05/2014, 17:00

In these last decade two researches at the frontiers of the particle physics and high energy astrophysics are unexpectedly moving along the cutting edge of the same detector technology. At one side precision the experiments on the direct search for absolute neutrino mass as well as detection of relic neutrinos or the search for its magnetic moment, at the other side the searches for hottest...

8. Neutrino observations with IceCube

Geraldina Golup (IIHE- Vrije Universiteit Brussel)

The IceCube Neutrino Observatory instruments a cubic kilometer of the Antarctic ice at the South Pole with a three-dimensional grid of light sensors in combination with a square kilometer surface array. The observatory was completed at the end of 2010, but the partially instrumented detector has been taking data since 2006. Several breakthroughs in the field have been accomplished, in...

50. High-Energy Neutrino Astronomy with the ANTARES Deep-Sea Cherenkov detector and with the future KM3NeT Telescope.

Antonio Capone (ROMA1)

In 2008 the ANTARES collaboration completed the construction of an underwater neutrino telescope in the Mediterranean Sea, located 40 km off the French coast at a depth of 2475 m. With an effective area for upward muon detection of about 0.05 km2, depending on neutrino energy, ANTARES is the largest neutrino detector currently operating in the Northern hemisphere. The experiment aims to...

77. Double Chooz: Towards the near detector phase

Lee F F Stokes (University of Tübingen)

Reactor anti-neutrino experiments have stood out in recent years with the measurement of the last mixing angle Theta 13. Double Chooz is one such experiment whose sensitivity will increase with the addition of the near detector, which is set to start data taking later this year. I will present results from three separate analyses, neutron capture on either Gd or H and a...

83. The OPERA experiment : new results

Chiara Sirignano (PD)

The OPERA experiment : new results. The OPERA experiment is designed to search for nu_mu->nu_tau oscillations in appearance mode through the direct observation of the tau lepton in nu_tau Charged Current interactions. The nu_tau CC interaction is identified through the detection of the τ lepton decay topology in the so called Emulsion Cloud Chamber (ECC), passive lead plates constituting...

12. Status of neutrino oscillations and sterile neutrinos

Carlo Giunti (INFN)

22/05/2014, 19:05

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. Taking into account also cosmological constraints, I present arguments in favor of 3+1 neutrino mixing with one sterile neutrino at the eV scale.

15. Are IceCube PeV neutrino events extraterrestrial or can be of atmospheric origin?

Anatoly Petrukhin (MEPhI)

22/05/2014, 19:30

Cascade showers with near PeV energies observed in the IceCube experiment in near horizontal direction gave a powerful pulse to discussions of their possible generation by extraterrestrial neutrinos. The reason is very simple. The expected neutrino flux of atmospheric origin is very small to produce such events. But if to take into account a possibility of production of a new state of matter...
