A Search for UHE Tau Neutrinos with IceCube
IceCube neutrino telescope tau neutrinos double bangs

2012/2/23
The first dedicated search for ultra-high energy (UHE) tau neutrinos of astrophysical origin was performed using the IceCube detector in its 22-string configuration. The search also had sensitivity to...
