Experimental Particle and Astro-Particle Physics Seminar

Stefanos Leontsinis (Universitaet Zuerich (CH))

Abstract: The Universe became transparent to neutrino’s approximately 1 second after the Big Bang. These neutrino’s are omnipresent with a density of around 300 cm-3. Frustratingly enough, they have never been observed since they have cooled down to a temperature of 1.9K, corresponding to an momentum of just several 100 µeV.   Within the PTOLEMY collaboration we are investigating techniques to observe these neutrino’s through their capture on tritium and its subsequent two-body beta decay.
