Inspecting a STAR module

Humberto Gonzalez is completing the final inspection of the last module for the STAR project.

Physicists achieve significant improvement in spotting accelerator-produced neutrinos in a cosmic haystack

Three vertical planes of sense wires stand in the center of this 3D chart that shows on the left how particles flying through the detector create electrons that drift to the sense wires of the detector, and on the right shows electric signals – the waveforms – that these wires will collect as a function of time. To the left, an incoming neutrino travels through the liquid argon of the time projection chamber, and it eventually splits into two charged particles that knock loose electrons in the liquid. To the right of the sense wires, waveforms are shown for the Y plane and the V plane.

Ground-breaking image reconstruction and analysis algorithms developed for surface-based MicroBooNE detector filter out cosmic ray tracks to pinpoint elusive neutrino interactions with unprecedented clarity.

Science corner – journey to the tiniest frontier

From Positively Naperville, May 24, 2021: A report on the April 7 Muon g-2 result announcement speculating that there must be new particles or forces that we have not yet discovered.

Fermilab scientist emeritus Mike Albrow offers historical context for the Muon g-2 results.

Prediction for magnetic moment of the muon informs a test of the standard model of particle physics

From Nature, May 5, 2021: The established theory of the standard model, and has passed a vast number of experimental tests with flying colors. But one such test — the determination of the magnetic moment of an elementary particle known as the muon — has resulted in a long-standing discrepancy between theory and experiment.

Kentucky group part of landmark physics experiment

From U.S. News and World Report, April 24, 2021: A team of University of Kentucky professors were part of a large-scale physics experiment at Fermilab showing results that point to a potential gap in the Standard Model of physics.

Moving the Muon g-2 magnet ring by ship

On July 19, 2013, the Muon g-2 magnet ring was moving up the Illinois River on its five-week journey from Brookhaven National Laboratory (Long Island, New York) to Fermilab. Scientists will announce the first results from the Muon g-2 experiments at 10 a.m. CDT on April 7, 2021. Muon G-2, Brookhaven National Laboratory Photo: Reidar Hahn, Fermilab

On July 19, 2013, the Muon g-2 magnet ring was moving up the Illinois River on its way from Brookhaven National Laboratory to Fermilab. It arrived in Lemont, Illinois, on July 21, 2013. Scientists will announce the first results from the Muon g-2 experiment at 10 a.m. CDT on April 7, 2021.

HL-LHC Accelerator Upgrade Project receives approval to move full-speed-ahead from Department of Energy

The U.S. Department of Energy has given the U.S. High-Luminosity Large Hadron Collider Accelerator Upgrade Project approval to move full-speed-ahead in building and delivering components for the HL-LHC, specifically, cutting-edge magnets and accelerator cavities that will enable more rapid-fire collisions at the collider. The collider upgrades will allow physicists to study particles such as the Higgs boson in greater detail and reveal rare new physics phenomena. The U.S. collaborators on the project may now move into production mode.

U.S. takes an important step toward quantum internet

From Inside Science, Nov. 12, 2020: A recent experiment has created a one-way quantum network between two labs, reaching a milestone on the path to creating a quantum internet. Fermilab Deputy Director Joe Lykken weighs in.
