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.

The LHC has now delivered over 4 inverse femtobarns (fb⁻¹) of data in 2011, of which CMS has collected 3.7 fb⁻¹.

The international physics masterclasses allow high-school students to spend a day at a research institute and analyse real data from high-energy physics experiments.

Next short Technical Stop will take place from Monday the 7th to Friday the 11th of November 2011

On the evening of 23rd September CMS welcomed, for the second successive year, young local students to point 5 for an experience they will never forget - and this time we joined forces with TOTEM.

Once upon a time, the only thing that traveled faster than the speed of light was gossip.

Thanks to the Internet, the whole physics world was watching on Friday when Dario Autiero, of the Institut de Physique Nucléaire de Lyon in France, in front of a palpably skeptical roomful of physicists, put a whole new category of speed demons on the table, namely the shadowy subatomic particles known as neutrinos.

Over the course of 16.5 hours ending Wednesday, Sept. 14, the CMS experiment recorded 113.4 inverse picobarns of data, more than three times the 36 inverse picobarns it recorded in all of 2010. The detector's data-taking efficiency was impressively high.

CERN was a special guest this year at the famous Ars Electronica festival in Linz, Austria. The theme of this year’s festival 'Origin — how it all begins' relates to the diverse research carried out at CERN.
