KATRIN and the Cosmic Neutrino Background Amand Faessler University of Tuebingen Germany Amand Faessler, Rastislav Hodak, Sergey Kovalenko, Fedor Simkovic:
Neutrino emission =0.27 MeV E=0.39,0.86 MeV =6.74 MeV ppI loss: ~2% ppII loss: 4% note: /Q= 0.27/26.73 = 1% ppIII loss: 28% Total loss: 2.3%
Do there exist sterile neutrino?
