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”...

The data reveal that the particle discovered at CERN continues to behave just like the Standard Model predicts Since the discovery of a Higgs boson by the CMS and ATLAS Collaborations in 2012, physicists at the LHC have been making intense efforts...

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...

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,...

One of the biggest unanswered questions of particle physics is why the mass of the Higgs boson is relatively small when the Standard Model suggests a more natural value would be many thousands of trillions of times higher. We don't know the answer...

Observing a phenomenon for the first time helps us fine-tune our understanding of the Universe. CMS physicists found such a phenomenon in September 2012 in proton-lead collisions, an observation that has since been reinforced by much more data from...
