After the wave of new and exciting results presented at the Winter conferences, the physics object and analysis groups are now focusing on the preparation of the CSA14 readiness test. We have clustered the CSA14 “analysis” efforts around a few…

From the desk of the CB Chairperson The CB Chair team is pleased to issue the second newsletter of the year. Draft minutes of the last CB meeting at CERN (28 Feb. 2014) are here. Some highlights of the CB meeting during this CMS Upgrade Week in…

The spring joint offline and computing week was held at CERN March 25-28 (the full agenda can be found in Indico). The main theme of the week was the readiness of the CMS computing infrastructure and the CMSSW software for the 2015 startup. The…

During the week of March 19, the CMS endcap muon upgrade passed a major milestone, with the completion of the certification of the final 36 Cathode Strip Chambers (CSC) for reinstallation on the CMS detector. The 72 chambers comprising the first…

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…

At the time when the minds of a few physicists are occupied with the design of a new detector, and the first meetings take place around a coffee table with detector engineers, the subjects discussed the most are the intensity and homogeneity of the…
