On 10^th January, a delegation from Serbia, led by President Boris Tadic, arrived at CERN to sign the agreement that would grant Serbia associate membership to CERN, as a step towards full membership.

Rolf Heuer, the Director General of CERN, welcomed back CERN personnel and users after the holiday period, at the annual New Year’s presentation held on 11^th January.

Serbian President Boris Tadic and Director General of the European Organization for Nuclear Research (CERN) Rolf Dieter Heuer signed on Tuesday in Geneva an agreement declaring Serbia a CERN Associate Member State.

Data are the currency of physics. As data accumulate, measurement uncertainty ranges narrow up to a certain point, increasing the potential for discoveries and making non-observations more stringent, with more far-reaching consequences.

Latest Higgs Search Results

CERN, 13th December 2011

The Collide@CERN Artist-in-Residence programme is currently seeking CERN scientists interested in engaging in thought-provoking and creative collaborations with visiting artists.

Latest TV news from CERN - LHC Computing Grid and upcoming results

Recently I participated in my second Science Hack Day (SHD), in San Francisco in November 2011. What is a Science Hack Day, you ask?

On 30^th October, scientists at CERN switched off the proton beams for the Large Hadron Collider. The completed 2011 run outdid all expectations, especially for luminosity, and provided the collider's four experiments with an unprecedented amount of data.

Introduction to the Higgs Boson and how CMS is looking for it

Science is closing in on the most elusive thing in the Universe.

On Saturday, 12^th November, a group of 240 young girls aged 11-14, sporting white lab coats, took the Science building of the University of Geneva by storm.

The 10- and 11-year-old children of Geneva town hall employees were allowed to skip classes on 10th November to participate in the nation-wide “Futur en Tous Genres” day and find out about different career prospects.

About CMS

CMS is an experiment at CERN's Large Hadron Collider (LHC) that is searching for new physics

CMS Detector

The CMS detector is a 5 storey-high digital camera recording hundreds of images per second of debris from LHC particle collisions

Physics Results

Physicists analyze LHC collision data recorded by the CMS detector and make all the research results freely available

At about half-past five in the evening on Sunday, 30^th October, an e-mail from Run Coordination to the CMS collaboration said:

Latest news from CERN, the LHC and Heavy Ion collisions ...

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.

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...

By combining their data ATLAS and CMS increase their sensitivity in the Higgs boson search

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.

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.

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.

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 windows into 21^st century science.

On Friday 7^th 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 achieved so far.

Three researchers behind the discovery that our Universe's expansion is accelerating have been awarded this year's Nobel prize for physics. Saul Perlmutter and Adam Riess of the US and Brian Schmidt of Australia will divide the prize. [...]

Watch the very first TV episode of "What's new @ CERN" featuring CMS physicist Yves Sirois, John Ellis and other physicists talking about the Higgs Boson, the Standard Model, Supersymmetry and neutrinos. "What's new @ CERN" is a new monthly outreach TV programme produced by CERN.
