Abstract. This is
the report of neutrino and astroparticle physics working group at WHEPP-8. We
present the discussions carried out during the workshop on selected topics
in the above fields
and also indicate progress made subsequently. The neutrino physics subgroup
studied the possibilities of constraining neutrino masses, mixing and CPT violation
in lepton sector from future experiments. Neutrino mass models in the context of
Abelian horizontal symmetries, warped extra dimensions and in the presence of
triplet Higgs were studied. Effect of threshold corrections on radiative magnification
of mixing angles was investigated. The astroparticle physics subgroup focused
on how various particle physics inputs affect the CMBR fluctuation spectrum,
and on brane cosmology. This report also contains an introduction on how to use
the publicly available code CMBFAST to calculate the CMBR fluctuations.
Keywords. Neutrino oscillation; neutrino mass models;
cosmic microwave background
radiation; dark
energy; branes.
