LHC

Scientists at CERN have found a way to learn more about the interior of neutron stars using the Large Hadron Collider. Researchers on the ALICE experiment are uncovering the properties of elusive hyperon particles hypothesized to be found inside neutron stars.

From CERN, Dec. 3, 2019: Large-scale scientific facilities, such as those for conducting particle physics research, are financed by society. A team of economists recently performed a cost-benefit analysis of upgrading the Large Hadron Collider. They concluded that the socioeconomic and cultural benefits gained from the project — not including potential scientific discoveries — exceed the total pecuniary investment.

This summer, physicist Larry Lee had festival-goers dancing to the sounds of science. He uses his musical training and an interest in collider machinery to create a new instrument of sorts. Using a piece of standard lab equipment, Lee has created a science-inspired, electronic music-backed light show.

Maria Teresa Dova has been instrumental in bringing scientists in Argentina new opportunities to participate in particle physics and astrophysics experiments, including one that co-discovered the Higgs boson.

From CERN, Oct. 7, 2019: The CMS collaboration has measured for the first time the variation, or “running,” of the top quark mass. The theory of quantum chromodynamics predicts this energy-scale variation for the masses of all quarks and for the strong force acting between them. Observing the running masses of quarks can therefore provide a way of testing quantum chromodynamics and the Standard Model.

The Large Hadron Collider is the world’s largest particle accelerator, known mostly for its discovery of the Higgs boson. The LHC will run for another two decades and will collect an enormous amount of data. In this 11-minute video, Fermilab scientist Don Lincoln explains how Fermilab is heavily involved in the upgrades required to make both the accelerator and the CMS detector a physics discovery powerhouse for the foreseeable future.

The Fermilab LHC Physics Center and Northwestern University recently hosted about 40 participants – experimentalists at the LHC experiments and theorists — for a two-day workshop titled “Multibosons at the Energy Frontier.” Discussions focused on strategies to best exploit the LHC data in the study of multiboson events.

For years, U.S. institutions have been working to upgrade the hardware in the behemoth CMS particle detector at the Large Hadron Collider, enabling it to profit fully from the LHC’s increasing collision energy and intensity. With CD-4 approval, the Department of Energy formally recognized that the USCMS collaboration, managed by Fermilab, met every stated goal of the upgrade program — on time and under budget.
