Standard Model

From Scientific American, October 2022: For several decades after the invention of the Standard Model, several physics measurements suggest that novel particles and forces exist in the universe. This article was originally published and titled, “When Particles Break the Rules” and includes the combined results from the Fermilab g-2 experiment and the previous trial at Brookhaven that add up to a probability of less than 0.01 percent that this anomaly is a statistical fluke.

From Brookhaven National Laboratory, October 11, 2022: Brookhaven National Lab announced yesterday that two of their scientists who led the “E821 g-2” experiment at BNL from 1990 through 2004 received the APS’s 2023 W.K.H. Panofsky Prize in Experimental Particle Physics. William M. Morse and Bradley Lee Roberts received the honor for their leadership and technical ingenuity in achieving a measurement of the muon anomalous magnetic moment with a precision suitable to probe Standard Model.

From Science News, August 15, 2022: W bosons are particles that transmit the weak force, which is responsible for certain types of radioactive decay. Last April, Fermilab researchers reported the W boson was more massive than predicted, hinting that something may be amiss with the standard model. Now a team of scientists with ATLAS at the LHC are reporting rare boson triplets which continues to test the standard model for any cracks.

In new papers by the CMS and ATLAS Collaborations, physicists detail high-precision results from their latest Higgs boson studies.

Scientists have learned a lot about the Higgs boson in the decade since they discovered it. But intriguing questions remain.

From The Big Think, June 29, 2022: Fermilab’s Don Lincoln highlights the 10 year anniversary of the Higgs boson, what we have learned in the past decade and what the next ten years of research and discovery may bring.

The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now?

The discovery of the Higgs boson inspired young people around the world to pursue a career in science and technology.

From NBC News, June 14, 2022: The faster and stronger LHC at CERN, scheduled to restart this summer, is stirring up renewed excitement in the discovery of particles that make up dark matter. While the LHC has been dormant for ten years, it has received upgrades while other accelerators like Fermilab’s Tevatron have made discoveries that point to possible “new physics.”

From PBS Space Time, May 25, 2022: Fermilab scientists spent almost a decade recording collisions in the Tevatron collider and another ten years analyzing data finding the W boson’s mass seems to be 0.01 percent heavier than expected. Now, understanding why the particle has mass puts the current Standard Model to the test.
