Resumen:
Recently H. Georgi has introduced the concept of unparticles in order
to describe the low energy physics of a nontrivial scale invariant
sector of an effective theory. We investigate its physical effects on
the neutrino flux to be detected in a kilometer cubic neutrino
telescope such as IceCube. We study the effects, on different
observables, of the survival neutrino flux after through the Earth, and
the regeneration originated in the neutral currents. We calculate the
contribution of unparticle physics to the neutrino-nucleon interaction
and, then, to the observables in order to evaluate detectable effects
in IceCUbe. Our results are compared with the bounds obtained by other
nonunderground experiments. Finally, the results are presented as an
exclusion plot in the relevant parameters of the new physics stuff.
