CERN Accelerating science

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:

A workshop on Alignment and Calibration (AlCa), organized by the PPD and DPG Coordinations, was held at CERN from the 17th to the 19th of March (https://indico.cern.ch/event/306000/).

The last few months have seen several important objectives of the CMS LS1 programme completed, giving increasing confidence in the final outcome.

The Tracker is a subdetector that is located closest to the collision point of the LHC’s particle beams inside the CMS detector. It must face an onslaught of billions of particles flying through it each second of operation.

After two years of planning, one year of implementation, and two million CHF worth of investments, the Tracker project has achieved its most important goal to enable the “Tracker Going Cold”.
