DONUT

A still with "Neutrino Flavors" written across the top. The o in flavors is a neutrino. Underneath it, the other two neutrino flavors illustrated, and a circle with a photo of a woman with dark hair and a pink and black top. Under her, it says "With guest Valerie Higgins." A woman with long brown hair holds an ice cream cone on the right side of the still.

Grab your bibs — in today’s tasty episode, we’re digging into neutrino flavors. Join Fermilab scientist Kirsty Duffy and archivist Valerie Higgins to meet the three flavors of neutrinos and learn how to catch a neutrino with a DONUT.

An international collaboration of scientists at the Department of Energy’s Fermi National Accelerator Laboratory will announce on July 21, 2000, the first direct evidence for the subatomic particle called the tau neutrino, the third kind of neutrino known to particle physicists.
