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…
A few of the results that CMS presented at this year’s Quark Matter conference were highlighted a couple of weeks ago in the CERN Courier article that was also posted on CMS news. That article was posted before the start of the conference, so it did…
This article originally appeared in the CERN Courier on 22 May 2014.
Although the CMS experiment was designed primarily for precise measurements in proton–proton (pp) collisions, in recent years it has demonstrated exceptional capabilities in…
The new top-quark mass measurement is the single most precise result as yet.
The mass of the top quark, the heaviest known elementary particle to-date, is one of the fundamental parameters of the Standard Model. Although the top quark mass is…
CMS has improved the constraints on the Higgs width, a fundamental property of this unique new particle, by more than two orders of magnitude.
Nearly two years after its discovery, there is much to learn about the Higgs boson observed by the CMS and…
In the past two weeks we had the final round of approvals for Moriond EW that is taking place during the week of Mar 17-22. The results approved are:
EXO-12-030: a search for pair-production of third generation scalar leptoquarks decaying to top…
The top quark remains, nearly 20 years after its discovery by the experiments at Fermilab’s Tevatron, the heaviest particle known. Its production and decays continue to be the subjects of extensive studies, both at the Tevatron and at the LHC. While…
At a seminar held at CERN this morning, the CMS collaboration presented several measurements of the properties of the Higgs boson discovered in July 2012. CMS showed for the first time strong evidence for the decay of Higgs bosons into fermions,…
