Description:

Title: Weighing the Neutrinos in the Cosmic Neutrino Background

Speaker: Lloyd Knox, (UC Davis)


Abstract:

The spectrum of masses of quarks and electrically charged leptons is quite well known, even if the origin of this spectrum remains a mystery. The neutrino sector, in contrast, still has much to be determined. Although we know mass differences from neutrino oscillation phenomena, we do not yet know the absolute mass scale. Our most precise upper limits come from effects of the cosmic neutrino background on cosmological observables. In this talk, I will discuss current constraints on the cosmic neutrino background, and neutrino masses in particular, from observations of the cosmic microwave background by the Planck satellite.I will also look toward what we can expect from future cosmological surveys.
