Objective
The aim of the proposal is the use of neutrinos from different astrophysical sources as probe for physics beyond the standard model (SM). The neutrino signal from a future galactic core-collapse supernova (SN) will provide us not only with unique information about the neutrino mixing parameters (like theta_13), but will also allow us to improve our understanding of the SN dynamics. We plan to study the influence of the dense SN medium on different reactions responsible for the formation of neutrino spectra, focusing on the nucleon-nucleonbremsstrahlung, as well as to analyze carefully the neutrino propagation in typical SN profiles. The detection of ultrahigh energy (UHE) neutrinos in detectors like AUGER offers the possibility to test the SM at energies well above those planned at accelerators. A signature of top-down models like super heavy dark matter and topological defects is the prediction of large UHE neutrino fluxes. The study of the UHE neutrino-nucleon interactions will allow moreover to disapprove scenarios with the Planck scale at the TeV scale. For both cases, detailed predictions for the experiments will be made. Cosmology is entering the precision era. A crucial input quantity for Bing Bang Nucleosynthesis(BBN) is the neutron lifetime, since the BBN results depend exponentially on it. We plan therefore to calculate the neutron lifetime within the framework of thermal field theory including 1-looP photoncorrections. The applicant will benefit from the expertise of the Astroparticle Physics group at Munich on Supernova physics and astrophysical implications of neutrinos and other weakly interacting particles, as well as the computational and bibliographical resources of the Max-Planck-Institut. It is also important to remark that the host group is part of the Special Field of Research SFB-375on Astroparticle Physics, installed by the German Research Council in 1995, which comprises different institutions in the Munich area. The experience of the applicant on Particle Physics and Astrophysics, in particular neutrino propagation in core-collapse supernovae, will nicely complement the current skills of the host group. He has recently collaborated with some of the group components, such as Dr. Michael. Kachelrie, and takes part in the ESF network on "Neutrino Physics" coordinated by his PhD supervisor, J. Valle, and where the host institution is involved.
