It is with great pleasure that we can announce that Nature has published our work on the measurement of the W boson mass with the CMS experiment even with a detailed commentary. It is a rare occurrence that CMS publishes…
The end of the year 2025 marked the end of an era, which had already started the year before with the departure of Josh Bendavid (now a permanent CERN staff). Zhangqier Wang and Kenneth Long left the PPC and are…
The High Luminosity (HL) version of the Large Hadron Collider (LHC) is at the top of the top priorities of the CERN management and of High Energy Physics all over the globe including the U.S. P5 recommendations and the European…
The Data Analysis School for members of the CMS experiment ‘CMSDAS’ is held yearly and this year, 2026, was no exception. The school was held at Fermilab’s LHC Physics Center and provided intensive hands-on training for new researchers on CMS…
We are still on the great cosmic scavenger hunt for dark matter, and the CMS experiment at CERN has been trying some delightfully weird detective work. Rather than only hunting for a single shiny new particle, we’re now also looking…
As usual, when the year comes to an end–bye bye 2025–we remember the good things from the year that just past, and hope for an even better New Year! CMS Sends out a greetings card to all groups to celebrate…
Not only did the LHC finish for the year, actually it was on December 10 already, they also finished with a little Christmas tree in the ‘Comments’ window. In that spirit: Thank you everybody for a very productive year and…
Private donors—including major foundations and prominent tech entrepreneurs—have pledged one billion dollars toward CERN’s proposed Future Circular Collider (FCC), marking the first major private investment in a flagship CERN machine. The FCC, would be the 90.7-km long circular successor to…
The recommendations for the update of the European Strategy for Particle Physics—discussed at the ESG closed meeting at the Monte Verità in Ascona, December 1-5, 2025—were just handed to CERN during the 225th meeting of its council. These recommendations outline…
The recent decision on Rhodes Scholars, one of the most prestigious scholarships around, included four students from MIT, which is wonderful, but even better it includes Sofia Lara, one of the inaugural generation of FCC-ee students participating in our undergraduate…
