On the detection of neutrino oscillations with Planck surveyor

The imprint of neutrino oscillations on the Cosmic Microwave Background (CMB) anisotropy and polarization power spectra is evaluated in a $\mathrm{\Lambda }$CHDM model with two active neutrino flavors, consistent with the structure formation models and the atmospheric neutrino oscillations data. We show the existence of a significant overlap between the region of the oscillation parameter space that can be measured by sc Planck surveyor and that implied by the atmospheric neutrino oscillations data.
