The CMS Week 2026 at CERN provided an opportunity for the collaboration to review the current status of the experiment, highlight recent scientific and technical achievements, and discuss preparations for the HL-LHC era. The opening plenary brought together reports from…
Today, May 19, 2026, marks an important milestone in the LHC project. The proton-proton collisions for the Run 3 period, that started on July 5, 2022, have officially completed. Run 3 has been a major success not only for the…
The University of Pisa recently hosted the electroweak (EWK) physics community for a highly engaging week of presentations, discussions, hackathon sessions, and of course a little fun as well. Much of the PPC cohort was present, a nice excuse to…
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…
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…
On November 4th at 22:10 the last 2025 proton-proton run of the LHC came to a close. As can be seen on the picture below, the LHC in the first third of the data taking fell a little behind the…
As of October 22, 2025, the Large Hadron Collider (LHC) has delivered 500/fb (inverse femtobarns) of integrated luminosity to its major experiments, ATLAS and CMS. The total delivered luminosity is a measure of the total number of particle collisions generated…
