Departmental Colloquium - Neutrinos: Measuring the Unexpected

Abstract:

Fifty years ago, Homestake chlorine experiment was proposed to observe solar neutrinos to see into the interior of the Sun and thus verify directly the hypothesis of nuclear energy generation in stars. The correct answer was obtained after a monumental effort made by scientists
from many disciplines. It came with a surprise: uncover the massive nature of neutrinos. More recently, verifying the existence of the hadronic cosmic accelerators that produce the highest energy cosmic rayes has uncovered  a new source of extragalactic neutrinos. I will overview the
neutrino physics involved in these fields and discuss the potential outcome of verifying other challenging questions in neutrino physics: a) How do most stars shine, b) Is the cosmic neutrino background around us today?, c) are neutrinos Majorana particles?
