제목: The hunt for high energy neutrinos with IceCube - more evidence for their astrophysical origin

연사: Prof. Albrecht Karle(U of Wisconsin)

일시: 2014년 5월 28일(수) 오후4:30

장소: 제1과학관 31214  첨단e+강의실

초록: The spectrum of cosmic rays includes the most energetic particles ever observed. The mechanism of their acceleration and their sources are, however, still mostly unknown. Observing astrophysical neutrinos can help solve this problem. Because neutrinos are produced in hadronic interactions and are neither absorbed nor deflected, they will point directly back to their source. The IceCube neutrino detector at the South Pole uses more than a billion tons of natural ice as a target for neutrino detection.
I will discuss searches for high-energy neutrinos (energies > 10^14 eV) with IceCube, which have recently provided the first evidence for a flux of neutrinos of beyond expectations from neutrinos generated in the Earth's atmosphere. 
This includes the detection of events with energies above 10^15 eV -- the highest energy leptons ever observed. 
I will review the recent findings obtained with IceCube as well as strategies underway that may help to shed more light 
on the origin of highest energy particles in the Universe.
