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…

CMS news from the past two weeks: YB-1 wheel closed; course now set towards physics re-start Stable Cold Tracker Operation Established (aka: the Tracker is Cool!) En route to 2015: Alignment and Calibration Workshop Physics analyses approved for…

The CMS control room is the heart of CMS operations, located at LHC point 5 in Cessy, France. Although the space was originally conceived to house the computing farm for the CMS Data Acquisition/High Level Trigger system, its intent was modified…

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: EXO-12-030: a search for pair-production of third generation scalar leptoquarks decaying to top…

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 main focus was the assessment of the needs and the plans for…

The last few months have seen several important objectives of the CMS LS1 programme completed, giving increasing confidence in the final outcome. In particular, the Tracker is running cold, the Phase 1 beam-pipe has passed acceptance tests at CERN…

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. To mitigate the effects…

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”. The Tracker was successfully (and safely!) operated “cold…

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…

From the desk of the CB Chairperson The CB Chair team is pleased to issue the first newsletter of the year. With Ian Shipsey, our former CB Chair now well installed in his new job, the team now consists of: Claudia-Elisabeth Wulz (acting CB Chair),…

Dear colleagues, CMS has been invited for a total of 21 talks (16 plenary and 5 parallel) at the workshop "Physics at LHC and beyond", in the framework of the 10th Rencontres du Vietnam, taking place from August 10-17 in Quy-Nhon, Vietnam. There's a…
