Query: Unparticle decay of neutrinos and it's effect on ultra high energy
  neutrinos   The unparticle is proposed by Georgi as a conceptual new physics beyond the
standard model to describe the low energy sector of a nontrivial scale
invariant sector of an effective theory. We consider the neutrino decay in
unparticle scenario and investigate the effect of such decay for the case of
ultra high energy neutrinos from GRB. The effect on the detection yield of
these neutrinos are also probed for a kilometer scale ice-Cerenkov detector.
