The ATLAS collaboration has begun to publish likelihood functions, information that will allow researchers to better understand and use their experiment’s data in future analyses.

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.

Fermilab scientists and engineers are developing a machine learning platform to help run Fermilab’s accelerator complex alongside a fast-response machine learning application for accelerating particle beams. The programs will work in tandem to boost efficiency and energy conservation in Fermilab accelerators.

High-intensity particle beams enable researchers to probe rare physics phenomena. A proposed technique called optical stochastic cooling could achieve brighter beams 10,000 times faster than current technology allows. A proof-of-principle experiment to demonstrate OSC has begun at Fermilab’s Integrable Optics Test Accelerator.

Matter and antimatter particles can behave differently, but where these differences show up is still a puzzle. Scientists on the LHCb experiment at the Large Hadron Collider study much more subtle differences between matter particles and their antimatter equivalents. A recent analysis allowed them to revisit an old mystery — an asymmetry between asymmetries.

From VICE, Dec. 17, 2020: Fermilab and partners have successfully teleported qubits across 22 kilometers of fiber in two testbeds. The breakthrough is a step towards a practical, high-fidelity quantum internet. Fermilab scientist and Quantum Science Program Head Panagiotis Spentzouris is quoted in this article.

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.

From APS Physics, Dec. 4, 2020: Scientists are finding ways to increase particle accelerator efficiency. One way to reduce cooling costs relies on a technique developed at Fermilab and Jefferson Lab.

From The New York Times, Dec. 8, 2020: Scientists are puzzling over why the universe is not as dark as expected. Fermilab scientist Dan Hooper weighs in.

A recent observation of an extremely rare subatomic process allows scientists to test the Standard Model’s boundaries.
