Innovative Detector Sees Its First Neutrinos

March 12, 2020
The Accelerator Neutrino Neutron Interaction Experiment at Fermilab, known as ANNIE, has seen its first neutrino events. (Neutrino events are interactions between neutrinos and water in the detector.) This milestone heralds the start of an ambitious program in neutrino physics and detector technology development. 

Explore Secrets of the Universe With UC Davis Physicist in Spectacular IMAX Movie

July 05, 2019
Venture from the tiniest subatomic particles to the grand scale of the galaxies and step inside the biggest machine ever built in Secrets of the Universe, a new IMAX movie. Secrets of the Universe will have its global premiere at the Smithsonian National Air and Space Museum in Washington, D.C., on July 10. 

No Evidence of a New Generation of Quarks (Yet)

April 03, 2019
Physicists working on the Compact Muon Solenoid experiment at the Large Hadron Collider at CERN, Switzerland have yet to find evidence of a fourth-generation heavy quark, the so-called “vector quark” or T quark. But they’re still looking and they have come up with some pretty ingenious ways to search.

Now Fully Funded, Innovative Nuclear Monitoring Project Moving Forward

January 25, 2019
WATCHMAN, an international partnership developing new methods for monitoring nuclear reactors, is now fully funded thanks to nearly $12.8 million (£9.7 million) from the United Kingdom’s Fund for International Collaboration. The project is also sponsored by the National Nuclear Security Administration, part of the U.S. Department of Energy.

UC Davis Physicists Help Detect Higgs Boson Decay

August 30, 2018
Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. A number of UC Davis physicists were involved in the observation.

Deep Underground Neutrino Experiment Breaks Ground

July 21, 2017
A special groundbreaking was held July 21 deep underground in South Dakota. Scientists, engineers and guests turned the first shovelfuls of the 800,000 tons of rock that will be excavated to build the Long Baseline Neutrino Facility (LBNF) at the Sanford Underground Research Facility.

LUX Dark Matter Detector Comes Up Empty

July 21, 2016
The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its silent search without detecting the missing matter of the universe.
