Neutrinos Group C June 29, 2014 ESHEP2014A Terrible HypothesisI have done a terrible thing. I have postulated a particle that cannot be detected. - Wolfgang Pauli (1930)

How can we detect neutrinos?Neutrinos have VERY SMALL interactions with other matter so we need VERY BIG detectors to see them.

Neutrino Experiments are AMAZING!

Where do neutrinos come from?radioactive decaynuclear reactions(inside the Sun, for example)nuclear reactorsparticle acceleratorscosmic ray interactionsOUTER SPACE

The IceCube Experiment

Interesting IceCube result:IceCube detected two very high energy neutrinos -- Bert and Ernie

Bert and Ernie have energy of ~ PeV (!!)

Ernie

Bert

How rare are the PeV neutrinos? -- a Highway AnalogyMost cars drive at the speed limit

but imagine a rocket ship driving down the highway!
