The photon-neutrino interaction in non-commutative gauge field theory and astrophysical bounds
Peter Schupp, Josip Trampetic, Julius Wess +1
In this letter we propose a possible mechanism of left- and right-handed neutrino couplings to photons, which arises quite naturally in non-commutative gauge field theory. We estim…
The CERN Axion Solar Telescope (CAST): status and prospects
CAST collaboration
The CAST experiment is being mounted at CERN. It will make use of a decommissioned LHC test magnet to look for solar axions through its conversion into photons inside the magnetic…
Astrophysical and Cosmological Neutrinos
G. G. Raffelt
We review the role of massive neutrinos in astrophysics and cosmology, assuming that the oscillation interpretation of solar and atmospheric neutrinos is correct. In particular, we…
Neutrino Masses in Astroparticle Physics
G. G. Raffelt
The case for small neutrino mass differences from atmospheric and solar neutrino oscillation experiments has become compelling, but leaves the overall neutrino mass scale m_nu unde…
Stars and Fundamental Physics
G. G. Raffelt
Stars are powerful sources for weakly interacting particles that are produced by nuclear or plasma processes in their hot interior. These fluxes can be used for direct measurements…
Monte Carlo Study of Supernova Neutrino Spectra Formation
Mathias Th. Keil, Georg G. Raffelt, Hans-Thomas Janka
The neutrino flux and spectra formation in a supernova core is studied by using a Monte Carlo code. The dominant opacity contribution for nu_mu and nu_tau is elastic scattering on…
