From Physics World, April 13, 2023: In recognition of World Quantum Day today, Physics World speaks with Fermilab’s Anna Grassellino, director of the U.S. Department of Energy’s Superconducting Quantum Materials and Systems Center. In this podcast, Grassellino explains how SQMS brings together people with a broad range of expertise to create new quantum technologies and how quantum sensors can be used to look for physics beyond the Standard Model.
beyond the Standard Model
For decades, scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed.
Scientists of the Collider Detector at Fermilab collaboration have achieved the most precise measurement to date of the mass of the W boson, one of nature’s force-carrying particles. The measured value shows tension with the value expected based on the Standard Model of particle physics.
The Standard Model is one of the most well-tested theories in particle physics. But scientists are searching for new physics beyond it.
Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning — but many researchers are not giving up on it yet.
From Scientific American, Dec. 16, 2020: Researchers have made the most precise measurement of one of the fundamental constants, called the fine-structure constant. Now all eyes are on Fermilab, where the first results of the Muon g-2 experiment are expected to provide the most precise experimental measurement of the muon’s magnetic moment. Alex Keshavarzi, scientist on the Muon g-2 experiment, weighs in on the significance of the measurement.
More than 3,500 researchers from around the world collaborate with Fermilab to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Here is a look at 10 ways Fermilab advanced science and technology in 2020.
From Sanford Underground Research Facility, May 26, 2020: Unwilling to ignore flaws in the Standard Model, physicists are looking for a new, more perfect model of the subatomic universe. And many are hoping that the international Deep Underground Neutrino Experiment, hosted by Fermilab, can put their theories to the test.
In their quest to discover physics beyond the Standard Model, physicists weigh the pros and cons of different search strategies.
A new result from the LHCb experiment could be an early indicator of an inconsistency in the Standard Model.
