The Sun in Hidden Photons    [PDF]

Javier Redondo

We present some aspects and first results of the emission of sub-eV mass
hidden photons from the Sun. The contribution from a resonant region below the
photosphere can be quite significant, raising previous estimates. This is
relevant for the Telescope for Hidden Photon Search, TSHIPS I, currently
targeting at meV-mass hidden photons with O(10^-6) kinetic mixing with the
photon. These particles could account for the large effective number of
neutrinos pointed at by the cosmic microwave background and other large-scale
structure probes, and are motivated in some scenarios of string theory.
