At about half-past five in the evening on Sunday, 30th October, an e-mail from Run Coordination to the CMS collaboration said: At 17:00 today the LHC dumped the last proton beams for the year to start the machine development period and to prepare…

The second episode of the monthly What's new @ CERN TV programme features Steve Myers, Director of Accelerators, on the LHC performance and plans, Yves Schulz of ALICE on Heavy Ion running, and more ... Watch show on YouTube  

Physicists at CERN's Large Hadron Collider (LHC) are analysing the results of their first attempt at colliding protons and lead ions. Further attempts at proton–lead collisions are expected over the next few weeks...

The source of energy for most of the life on our planet originates from proton-proton collisions at the core of the Sun, which occur at an energy (or temperature) about a billion times less than the collision energy of the LHC. Due to emission of…

The Large Hadron Collider will spend four weeks probing the conditions of the early universe in better detail than ever before, as it takes a break from the hunt for the Higgs boson...

At 17:00 on Sunday 30th October the LHC dumped the last proton beams for the year to start the machine development period and to prepare for heavy ion running. This means that we have come to the end of proton operation for 2011. In 2011 the LHC…

The machine just announced going to Proton Physics today in the afternoon since ~5pm. The 25ns Machine Development has been postponed to Monday. Subsystems experts, please make sure that we are ready for physics and running fine. Cheers, RFMs…

Grab a can of soda, shake it thoroughly, and open it up. What do you get? It’s an explosion of fizz. A similar phenomenon in the subatomic world might help us probe the nature of fundamental particles. Scientists have spent centuries searching for…

The LHC has now delivered 5 inverse femtobarns (fb−1) of data in 2011, of which CMS has collected 4.53 fb−1.

This year, for the first time, the winners of the Italian Physics, Mathematics and Informatics Olympiads received an unforgettable reward from the Italian Ministry of Education, University and Research (MIUR): a trip to CERN. The National Institute…

You have to be curious and creative to work for a project like CMS. Without these qualities, it would be impossible to build an instrument of its complexity. The CMS detector is a marvellous instrument at the forefront of technology and will open…

On Friday 7th October the LHC delivered, for the first time in the history of High Energy Physics, proton-proton collisions at the design frequency of 40 MHz, with bunches of protons colliding every 25 nanoseconds (ns), doubling the frequency…
