Triple threat: The first observation of three massive gauge bosons produced in proton-proton collisions

    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.

    Simulating subatomic physics on a quantum computer

      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.

      Jump into Computer Science Education Week

        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.

        Physics books of 2020

        How do the questions Galileo faced in the 17th century relate to those posed in our own era? What is our place in this vast realm of existence? How will spacetime come to an end?Symmetry writer Mike Perricone’s favorite physics books of 2020 cover an impressive span of time: from the very beginning of our universe until the very end.

        What tree rings can tell us about the spectacular death of stars

          From CNN, Nov. 28, 2020: The explosion of a supernova is so powerful that modern telescopes can see it half a universe away. A cautious person might wonder, “What would happen to Earth if this happened to a nearby star?” In this article, Fermilab scientist Don Lincoln discusses a paper from University of Colorado at Boulder’s Robert Brakenridge, who claims that he has found evidence here on Earth of nearby supernovae. What form does this evidence take? Ancient radioactive tree rings.

          Un gigantesco laboratorio de neutrinos en Dakota del Sur a kilómetro y medio de profundidad

            From Público, Nov. 24, 2020: Homestake fue la mayor y más profunda mina de oro de de Norteamérica hasta que se cerró en 2002 tras 125 años de funcionamiento. Este remoto lugar de Dakota del Sur se convirtió oficialmente en 2007 en un laboratorio subterráneo de física fundamental, aunque ya mucho antes se habían instalado en sus profundas cavernas algunos experimentos, incluido uno que mereció el premio Nobel. Ahora se anuncia la nueva etapa para convertir la mina en sede del megaproyecto científico más importante de las últimas décadas en Estados Unidos, el Long-Baseline Neutrino Facility, dedicado a estudiar las partículas fundamentales llamadas neutrinos.
