Quark Matter 2014: the full crop from CMS
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.

Quark Matter 2014: news from CMS
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 studying interactions of heavy nuclei.

CMS presents a new precise measurement of the top-quark mass
The new top-quark mass measurement is the single most precise result as yet.
-
A bound on the natural width of the Higgs boson
CMS has improved the constraints on the Higgs width, a fundamental property of this unique new particle, by more than two orders of magnitude.
-
CMS observes new single-top production mode
The top quark remains, nearly 20 years after its discovery by the experiments at Fermilab’s Tevatron, the heaviest particle known.
-
CMS presents evidence for Higgs decays to fermions
Several measurements of properties of the Higgs unveiled at CERN seminar.

Recent results on SUSY searches from CMS
CMS presented new results of searches for signatures of supersymmetry (SUSY) at the LHCP conference held in Barcelona, Spain in May and at the EPSHEP conference held in Stockholm, Sweden in July.

A very rare decay has been seen by CMS
CMS has seen an important rare decay predicted by the Standard Model

Supersymmetric glue: the search for gluinos
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.
