Neutrino physicist wins 2026 Nobel Physics Prize

Francis Halzen of University of Wisconsin-Madison led development of IceCube Neutrino Observatory.

The short version

• “It was a great surprise, and I obviously didn’t expect it,” Halzen said during a news conference in Stockholm, Sweden, speaking by phone from Italy.
• While the Nobel was awarded to Halzen, he emphasized that his work was the result of a “large collaboration” with other researchers.
• “This reflects on the really courageous people who joined me in this project when really no respectable conservative physicist would have joined me.

What happened

But many talented people did, and that’s why I’m here,” he said . Neutrinos were first proposed by Wolfgang Pauli in a 1930 letter to colleagues.

Why it matters

He was trying to explain some baffling experimental results on radioactive beta decay in atomic nuclei, where energy appeared to be missing—something he deemed (correctly) to be impossible.
