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.
Until recently, scientists had never detected black holes in the “mass gap.” Now, particle physicists are exploring ideas beyond the Standard Model that could explain them.
From Forbes, Dec. 14, 2020: Fermilab scientist Don Lincoln explains a new measurement performed by scientists at University College London that has the potential to cause researchers to look again at theories of electromagnetism. The team studied the behavior of an exotic atom called “positronium” and found a surprising difference between the prediction and measurement energy level of a specific energy transition. Positronium is an atom that consists solely of an electron and an antimatter electron.
From D La Repubblica, Dec. 12, 2020: Deputy Chief Technology Officer e vicedirettrice della divisione di fisica applicata e tecnologia dei superconduttori del Fermilab, negli Usa. Sta costruendo il computer più potente del mondo. L’abbiamo scelta insieme a voi tra 20 finaliste.
From D La Repubblica, Dec. 10, 2020: È italiana, ha solo 39 anni, è Deputy Chief Technology Officer al Fermilab di Chicago, dove sta progettando il computer quantico più potente mai creato al mondo. Incontro di Valeria Palermi, direttrice di D, con Anna Grassellino, Donna dell’Anno 2020.
From Phys.org, Dec. 7, 2020: The CMS collaboration, a worldwide group of scientists studying particle collisions at CERN’s Large Hadron Collider, has recently observed the production of three massive gauge bosons in proton-proton collisions for the first time ever. Northwestern University postdoc and Fermilab Distinguished Researcher Saptaparna Bhattacharya talks about the triboson search.
When two heavy ions collide inside a particle accelerator, they produce a near-perfect fluid through which an assortment of fundamental particles swim. For scientists to accurately simulate even a tiny drop of this hot and dense subatomic brew with a classical computer, it would take longer than the age of the universe. Scientists show how quantum computing could be a game-changer in our understanding of quantum processes.
From DOE, Dec. 9, 2020: Computer Science Education Week is aimed at inspiring students to discover computer science activities and careers. The national laboratories, including Fermilab, are scheduled to host a number of activities to highlight The Department of Energy’s efforts, including increasing access to computer science education, building computational literacy, and growing the cyber workforce of the future.
