CERN Accelerating science

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.

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.

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.

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 new top-quark mass measurement is the single most precise result as yet.

CMS has improved the constraints on the Higgs width, a fundamental property of this unique new particle, by more than two orders of magnitude.

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 magnetic field, the hermetic nature of the calor

CMS news from the past two weeks:

The CMS control room is the heart of CMS operations, located at LHC point 5 in Cessy, France.

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:
