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…

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…

12 October 2017 For most of each operational year, the Large Hadron Collider (LHC) typically smashes protons together to generate vast amounts of data for physicists to analyse. These proton-proton (pp) collisions were responsible, for example, for…

The 10th International workshop on top quark physics, TOP2017, was held in Braga, Portugal, from September 17th to 22nd, 2017 and brought together a number of experimentalists and theorists from all over the world. The CMS Collaboration presented…

Harvesting of the large 13 TeV data set delivered by the LHC in 2016 and collected with the CMS detector continues, with 20 new results to be presented at the EPS 2017 conference, adding to the more than 60 results already presented at the 2017…

The exploitation of the LHC data collected by CMS is continuing successfully, with more than 35 new results presented at the Moriond 2017 conference, most of which used the full 2016 luminosity. These results cover all the research lines of the…

The Rencontres de Moriond – Electroweak (Moriond EW) takes place this week in La Thuile, Aosta Valley, Italy, where the CMS Collaboration will present more than 30 new results approved since the December 15 seminar at CERN. First measurements of the…

The first phase of collisions following the LHC restart earlier this year has provided CMS with a wealth of data at a new energy frontier of 13 TeV. This centre-of-mass collision energy, the highest ever achieved by a particle accelerator, is…

CMS Experiment, CERN 13 May 2015 UPDATE 2: The CMS data used in the result below have been analysed together with LHCb's data to obtain a combined result that is now published in Nature. Including all of the data taken by both experiments at 7 and 8…

Among the leading candidates to describe physics beyond the standard model of particle physics is Supersymmetry, a new symmetry that posits the existence of a partner particle for each known particle in the standard model. Supersymmetry, or “SUSY”…
