Theoretical physicist James D. “BJ” Bjorken, theoretical physicist at SLAC and Stanford, passed away on Aug. 6. He was born in Chicago and in 1979, he left the SLAC and Stanford faculties to become associate director for physics at the Fermilab, saying he wanted to learn more about the accelerator side of things

There are patterns seen in quarks and leptons that remain unexplained, but it can be hypothesized that quarks and leptons might be created of still smaller particles. Does the Standard Model allow for an even smaller layer of matter to exist?

Fermilab scientists have taken a major step in preparing for the Deep Underground Neutrino Experiment with a prototype particle accelerator. The 2×2 detector prototype has four liquid argon modules arranged in a square whereas the DUNE detectors will have 35 liquid argon time projection chambers, allowing scientists to track the movements of particles and determine their physical properties.

The prototype of a novel particle detection system for the international Deep Underground Neutrino Experiment successfully recorded its first accelerator neutrinos, providing a first look at the ability of this innovative technology to handle large numbers of the mysterious particles’ interactions.

Listen to the podcast story of Dr. Helen Edwards, who was a Fermilab particle physicist who led the design and construction of the Tevatron to probe deeper into the atom than anyone had gone before.

Pantaleo Raimondi’s illustrious career brought him to some of the world’s most prestigious particle physics institutions. In January, Raimondi continued this journey as he took over the role of project director for Fermilab’s newest, more powerful particle accelerator.

Neutrinos were first detected by Los Alamos researchers in 1956 and today very little is known about these elusive particles. Today, Los Alamos is part of the international collaboration of DUNE which aims to launch the most intense neutrino beam in the world.

During a ceremony at ICHEP, Ngadiuba’s contributions to ultra-fast machine learning techniques and anomaly detection were recognized by the International Union of Pure and Applied Physics.

Fermilab has twin laboratories that will probe superconducting qubits: QUIET is a new detector 100 meters underground and its counterpart is on the surface called LOUD, which began operations in 2022. The differences between the two detectors’ observations will allow researchers to assess how cosmic radiation affects qubit performance.

Physicists use large particle detectors filled with liquid argon to study neutrinos. Brazilian scientists discovered that a commercially available material can significantly reduce the amount of nitrogen in liquid argon, which improves the detection of neutrino interactions.
