Beamtime at the LHC
First proton beams are in the machine for this year, 2024. It is always an exciting moment, even if we have done this for many many years already. To get a machine with 1232 dipole magnets and even more focusing…

SUEP Hits Social Media
After the PAS was released in December, and in preparation for the real paper, a briefing describing the SUEP offline search has been made public on the CMS and is advertised by the CMSExperiment accounts on social media:
CMS Week and Spokesperson Election
The first CMS week of 2024 took place during the second week of February, Monday 5th to Friday 9th. It was a rather busy week with a full agenda including a large number of plenary and parallel sessions. CMS is…
Chronicle of a VIP visit
On January 10-12 our MIT Physics department head, Prof. Deepto Chakrabarty embarked on a special journey to CERN. MIT is making a notable impact at CERN through projects like AMS, Isolde, LHCb, CMS, and theory research. It was a privilege…
SUEPs – Searching for the Hidden Valley
We are happy to announce the public release of the first dedicated search for soft unclustered energy patterns (SUEPs) at the LHC. The search uses the 13 TeV pp collision data collected by the CMS detector in 2016-2018. This effort…
¡Adéu, Martí!
After 8 months of hard work, coffee, and tacos, Martí leaves the PPC having submitted his Master’s Thesis: a huge congratulations! A visiting student from ETH Zurich, Martí worked alongside our very own Mariarosaria and Kyungseop to study rare Higgs…
MIT’s Dean of Science visits CMS
November 1, 2023 was the day that our own Nergis Mavalvala, our Dean came to CERN for the first time. Bolek the director of the Laboratory for Nuclear Science had invited her and she accepted, curious as we learned during…
YETS started
The Year End Technical Stop or for the LHC experts YETS is in effect as of today (October 30, 2023). The year has finished with an exciting Heavy Ion run which started slow but eventually picked up the pace and…
Better muon triggers for charm and beauty studies in Run 3
Run 2 results attracted significant interest in heavy flavor physics at the LHC. The highlights of these findings include a 3-sigma discrepancy in the decay rate of the B meson into charm mesons with either a muon or a tau,…
Prompt CMS data processing reaches new record
The LHC program for this year will be concluded with one month of Heavy Ion (PbPb) collisions. It enables us to study the properties of matter in extreme conditions (a trillion times denser than the core of the sun) and…
