First results from the Muon g-2 experiment at Fermilab have strengthened evidence of new physics. The centerpiece of the experiment is a 50-foot-diameter superconducting magnetic storage ring, which sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the precession (or wobble) of muons as they travel through the magnetic field. Photo: Reidar Hahn, Fermilab
First results from Fermilab’s Muon g-2 experiment strengthen evidence of new physics
The first results from the Muon g-2 experiment hosted at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics.

ALPHA cools antimatter using laser light for the first time
The ALPHA collaboration at CERN has succeeded in cooling down antihydrogen atoms – the simplest form of atomic antimatter – using laser light. The technique, known as laser cooling, was first demonstrated 40 years ago on normal matter and is a mainstay of many research fields.

Intriguing new result from the LHCb experiment at CERN
Geneva. Today the LHCb experiment at CERN announced new results which, if confirmed, would suggest hints of a violation of the Standard Model of particle physics. The results focus on the potential violation of lepton flavour universality and were announced at the Moriond conference on electroweak interactions and unified theories, as well as at a seminar held online at CERN, the European Organization for Nuclear Research.

Fermilab delivers final superconducting particle accelerator component for world’s most powerful laser
Today, the Department of Energy’s Fermilab shipped its final superconducting component for the new particle accelerator for the Linac Coherent Light Source II, or LCLS-II, at DOE’s SLAC National Accelerator Laboratory.
The cryomodule — the major component of the linear accelerator — is the final one required for the LCLS-II project, which will be the world’s brightest X-ray laser when complete.

IceCube detection of a high-energy particle proves 60-year-old theory
On December 6, 2016, a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly decayed into a shower of secondary particles. The interaction was captured by a massive telescope buried in the Antarctic glacier, the IceCube Neutrino Observatory.

Dr. Nigel Smith appointed as next Director of TRIUMF
VANCOUVER, B.C. – Dr. Nigel Smith, Executive Director of SNOLAB, has been selected to serve as the next Director of TRIUMF. Succeeding Dr. Jonathan Bagger, who departed TRIUMF in January 2021 to become CEO of the American Physical Society, Dr. Smith's appointment comes as the result of a highly competitive, six-month international search. Dr. Smith will begin his 5-year term as TRIUMF Director on May 17, 2021.

Compelling evidence of neutrino process opens physics possibilities
The COHERENT particle physics experiment at the Department of Energy’s Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. Because neutrinos are electrically neutral and interact only weakly with matter, the quest to observe this interaction drove advances in detector technology and has added new information to theories aiming to explain mysteries of the cosmos.

RHIC Run 21: Pushing the Limits at the Lowest Collision Energy
UPTON, NY—Accelerator physicists are preparing the Relativistic Heavy Ion Collider (RHIC), a DOE Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, for its 21st year of experiments, set to begin on or about February 3, 2021. Instead of producing high-energy particle smashups, the goal for this run is to maximize collision rates at the lowest energy ever achieved at RHIC.

Dark Energy Survey makes public catalog of nearly 700 million astronomical objects
The Dark Energy Survey, a global collaboration including the Department of Energy’s Fermi National Accelerator Laboratory, the National Center for Supercomputing Applications, and the National Science Foundation’s NOIRLab, has released DR2, the second data release in the survey’s seven-year history. DR2 is the topic of sessions today and tomorrow at the 237th Meeting of the American Astronomical Society, which is being held virtually.
