More on crinkles in the last scattering surface

Inhomogeneous recombination can give rise to perturbations in the electron number density which can be a factor of 5 larger than the perturbations in baryon density. We do a thorough analysis of the second order anisotropies generated in the cosmic microwave background due to perturbations in the electron number density. We show that solving the second order Boltzmann equation for photons is eq...

On the Width of the Last Scattering Surface

We discuss the physical effects of some accelerated world models on the width of the last scattering surface (LSS) of the cosmic microwave background radiation (CMBR). The models considered in our analysis are X-matter (XCDM) and a Chaplygin type gas. The redshift of the LSS does not depend on the kind of dark energy (if XCDM of Chaplygin). Further, for a Chaplygin gas, the width of the LSS is ...

Looking for cosmic neutrino background

*Correspondence: Chiaki Yanagisawa, Department of Physics and Astronomy, Stony Brook University, NY 11794-3800, USA e-mail: chiaki@ nngroup.physics.sunysb.edu Since the discovery of neutrino oscillation in atmospheric neutrinos by the Super-Kamiokande experiment in 1998, study of neutrinos has been one of exciting fields in high-energy physics. All the mixing angles were measured. Quests for (1...

Neutrino Oscillations and Neutrino - Electron Scattering

One expects that, in general, neutral-current processes will be completely unaffected by the oscillation of neutrinos among their various possible flavors (v , v , v ses presumably preserve neufring f&ii, >. After all, these procesand are independent of that flavor. Thus, oscillation of neutrinos from one flavor to another will not change any neutral-current cross sections. Indeed, even if the ...

Neutrino Nucleus Scattering

The status of the theoretical description of the neutrino-nuclear interaction for low and intermediate energies is reviewed and its results are compared with the existing data. Particular emphasis is on C, the ingredient of liquid scintillator, and on O, the main component of the water Čerenkov detectors. First, I show that the data on the exclusive process populating the ground state of N are ...
