Following the discovery of the Higgs boson with a mass of approximately 125 GeV by the ATLAS and CMS collaborations at the Large Hadron Collider, extensive studies have confirmed its central role in the spontaneous breaking of electroweak symmetry in…
The first CMS week of 2025 took place during the first part of February, Monday 10th to Friday 14th. It was a rather busy week with a full agenda including a large number of plenary and parallel sessions. CMS is preparing the 2025…
In 2024, CMS collected around 50 PB of raw data and generated more than 75 PB of simulated data. Together with prompt processing, this amounts to more than 150 PB of new data. Using such an enormous amount of data…
In the world of particle physics, every discovery -or lack thereof- can make waves. Recently, the CMS collaboration has published the first diboson paper in the Physics Letters B journal using the LHC Run 3 data, specifically the production of…
Visiting MIT for the fall semester, Cecilia concluded her experience here on the week of Thanksgiving. She will return to her home institution of CIEMAT to begin work on her thesis after 3 months of great physics and memorable experiences.…
Today, November 23, 2024, the LHC crew at CERN completed the running of the Large Hadron Collider for 2024, which was the tenth year and resulted in a record data accumulation. The beginning of 2024 went picture book perfect: when…
After the initial proton-proton reference run has been completed reasonably smoothly CMS is now really logging Heavy Ion collisions. As usual in those relatively short periods the CMS control room in Meyrin is full of the Heavy Ion folks. This…
I’ve been a postdoctoral researcher at MIT for three years, but I’ve spent almost all of that time in Geneva, Switzerland working with many other members of the PPC group in our bustling corridor of Building 32 on the CERN…
The LHC has just dumped its last proton-proton collision fill for 2024. Below is the final proton run picture where the news was announced. The year has seen a new record in data taken in a given amount of time…
CMS has a rich heavy-ion physics program covering measurement of jet quenching, quarkonium suppression, heavy flavor, flow correlations, and forward physics. Many of the physics goals involve rare probes of the quark-gluon plasma that rely on large data samples. The…
