Best Precision Yet for Neutrino Measurements at Daya Bay

In the Daya Bay region of China a research project is underway to study ghostlike, elusive particles called neutrinos. Today, the international Daya Bay Collaboration announces new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment, significant as the first equal partnership between the U.S. and China in a major physics project, continues to be one to watch.

Cosmic Mystery Deepens with Discovery of New Ultra-High-Energy Neutrino

Evidence of a fourth ultra-high energy neutrino—the highest-energy neutrino yet—has been detected by the South Pole-based IceCube experiment.

Notes from the Particle Physics Underground

The town of Lead South Dakota has a hidden gem: an enormous, underground mine that’s been retrofitted to accommodate large-scale particle physics experiments. These slideshows and videos give a sense of what it’s like to descend 4,850 feet below the surface and work on projects that could shine light on fundamental truths about the universe.

New Visitor Center in South Dakota Highlights Underground Science

The Sanford Lab Homestake Visitor Center, a facility that highlights Homestake Mine’s gold and silver past and particle physics future, held its grand opening ceremony on June 30.

For Ultra-cold Neutrino Experiment, a Successful Demonstration

An international team of nuclear physicists announced the first scientific results from the Cryogenic Underground Observatory for Rare Events (CUORE) experiment. CUORE is designed to confirm the existence of the Majorana neutrino, which scientists believe could hold the key to why there is an abundance of matter over antimatter.

Creating the Coldest Cubic Meter in the Universe

As part of an international collaboration, Berkeley Lab scientists have helped create the coldest cubic meter in the universe. The cooled chamber—roughly the size of a vending machine—was chilled to 6 milliKelvin or -273.144 degrees Celsius in preparation for a forthcoming experiment that will study neutrinos, ghostlike particles that could hold the key to the existence of matter around us.

Hide & Seek: Sterile Neutrinos Remain Elusive

The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a possible new type of neutrino beyond the three known neutrino “flavors,” or types.

Searching for Cosmic Accelerators Via IceCube

In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider at CERN, but scientists don’t know what or where these cosmic accelerators are. New results reported from “IceCube,” the neutrino observatory buried at the South Pole, may show the way.

Searching for Cosmic Accelerators Via IceCube

New results from IceCube, the neutrino observatory buried at the South Pole, may show the way to locating and identifying cosmic accelerators in our galaxy that are 40 million times more powerful than the Large Hadron Collider at CERN.

Berkeley's Kam-Biu Luk Wins Panofsky Prize for Daya Bay Experiment

Berkeley Lab and UC Berkeley physicist Kam-Biu Luk has been named by the American Physical Society to be a recipient of the 2014 W.K.H. Panofsky Prize in experimental particle physics. He and Yifang Wang of China’s Institute of High Energy Physics will share the prize for their leadership roles in the Daya Bay neutrino experiment.
