In November 2018 the proton-proton running of the LHC Run 2 ended. The data collected in 2018 is the largest sample ever collected at the LHC. Just under three months after the final proton proton collisions were recorded, the CMS collaboration has…

The top quark is the heaviest particle in the standard model, and since its discovery in 1995 at the Tevatron collider at Fermilab, its study has become prominent in furthering our understanding of fundamental physics. At the Large Hadron Collider,…

The discovery of the Higgs boson in 2012 at the Large Hadron Collider marked the beginning of a comprehensive experimental program to measure its properties. Milestones since then include the observation of Higgs boson decays to γγ, ZZ, WW, ττ as…

The CMS collaboration is presenting over 25 new results at the 39th International Conference on High Energy Physics (ICHEP 2018) taking place in Seoul, South Korea from July 4th-July 11th, 2018. A key highlight is a comprehensive combination of…

Do you remember where you were on July 4th, 2012? If you are an American, perhaps it's not so difficult to recall that day. You might have been enjoying a barbecue with your friends and family to celebrate the national Independence Day. For others,…

The CMS collaboration continues with its rich harvesting of the large Run 2 dataset with 21 new results presented at the LHCP 2018 conference in Bologna, Italy. The results cover a wide assortment of topics and range from precision measurements of…

The first observation of the simultaneous production of a Higgs boson with a top quark-antiquark pair is being published today in the journal Physical Review Letters (PRL). This major milestone, first reported by the CMS Collaboration in early April…

The CMS collaboration came to this year’s Quark Matter conference with fourteen new results, never shown before, and five other results recently submitted for publication. The majority of them exploit the high luminosity 8.16 TeV pPb, and 5.02 TeV…

Observation of ttH production   The observation of a Higgs boson in 2012 at the Large Hadron Collider marked the starting point of a broad experimental program to determine the properties of the newly discovered particle. In the standard model, the…

Analysis of the large dataset delivered by the LHC in Run 2 continues with more than 25 new results from the CMS collaboration presented at the 2018 Rencontres de Moriond conference. Most of these results will be published shortly and will add to…

It has been a little over seven (and a half) years since the LHC started delivering collisions to CMS for physics analysis, and just a few days ago we published our 700th research paper. To celebrate this achievement, we thought we would give you a…
