Rediscover the Standard Model of particle physics and much more with open data from the Large Hadron Collider Today, the CMS Collaboration at CERN has released more than 300 terabytes (TB) of high-quality open data. These include over 100 TB, or 2.5…

The LHC is back online! This morning we saw first beams splashes in the CMS experiment as the beam was threaded through the LHC full circle! "This data is already useful to understand details about the behaviour of the new CMS Trigger, and we are…

The Rencontres de Moriond – Electroweak (Moriond EW) takes place this week in La Thuile, Aosta Valley, Italy, where the CMS Collaboration will present more than 30 new results approved since the December 15 seminar at CERN. First measurements of the…

Fermilab’s Joel Butler will take the reins of the CMS collaboration in September, after having been elected as its new spokesperson during the last CMS Week. On 10 February, members of the CMS Collaboration Board, the “parliament” of the…

(French version below) (Geneva, 26 February 2016) – The inspiration for the latest art exhibition at the Cité du Temps came from a scientific experiment the height of a six-floor building, built to the precision of the thickness of a human hair. “…

The first phase of collisions following the LHC restart earlier this year has provided CMS with a wealth of data at a new energy frontier of 13 TeV. This centre-of-mass collision energy, the highest ever achieved by a particle accelerator, is…

Michel Della Negra and Tejinder (Jim) Virdee have been recognized for their work on CMS by their respective national physics institutes. Michel has been awarded the 2014 prix André Lagarrigue for his “qualités exceptionelles de batisseur de…

CMS has been taking collision data since the 13TeV startup of the LHC on 3 June. During this period, the CMS magnet has been kept off due to an issue with the cooling system, so the beams have been used to calibrate and time-in the electronics of…

  From the CERN Press Release: Today, CERN's Large Hadron Collider (LHC) started delivering physics data for the first time in 27 months. After an almost two year shutdown and several months re-commissioning, the LHC is now providing collisions…

From the CERN website: Last night, protons collided in the Large Hadron Collider (LHC) at the record-breaking energy of 13 TeV for the first time. These test collisions were to set up systems that protect the machine and detectors from particles…

CMS Experiment, CERN 13 May 2015 UPDATE 2: The CMS data used in the result below have been analysed together with LHCb's data to obtain a combined result that is now published in Nature. Including all of the data taken by both experiments at 7 and 8…
