When the Large Hadron Collider is in operation, the cavern containing the CMS detector is an extremely inhospitable place, due to the high-energy radiation produced by the collisions. Even after a LHC fill finishes, some residual radioactivity can…

On 1 September 2018, a new spokesperson and two deputies took over at the helm of the CMS experiment for a period of two years. The new team will lead the CMS Experiment through an important period that will include analysis of the CMS 2018 data and…

There is no doubt that on the last Friday night of September many researchers are not only awake but also very busy explaining what they do to the public – it’s European Researchers Night. This year, it was for the fourth consecutive year that CMS…

Last week, CERN hosted the first workshop on High Energy Theory and Gender focusing on recent developments in theoretical high-energy physics and cosmology, and discussed issues of gender and equal opportunities in the field. Unfortunately, one of…

Congratulations to four CMS scientists, Kerstin Borras, David Saltzberg, Robin Erbacher and Paul Padley, who were elected as American Physical Society (APS) Fellows in 2018 for their exceptional contributions to the field of physics. The American…

The discovery of the Higgs boson in 2012 at the Large Hadron Collider marked the beginning of a comprehensive experimental program to measure its properties. Milestones since then include the observation of Higgs boson decays to γγ, ZZ, WW, ττ as…

The CMS collaboration is presenting over 25 new results at the 39th International Conference on High Energy Physics (ICHEP 2018) taking place in Seoul, South Korea from July 4th-July 11th, 2018. A key highlight is a comprehensive combination of…

Do you remember where you were on July 4th, 2012? If you are an American, perhaps it's not so difficult to recall that day. You might have been enjoying a barbecue with your friends and family to celebrate the national Independence Day. For others,…

The CMS collaboration continues with its rich harvesting of the large Run 2 dataset with 21 new results presented at the LHCP 2018 conference in Bologna, Italy. The results cover a wide assortment of topics and range from precision measurements of…

The first observation of the simultaneous production of a Higgs boson with a top quark-antiquark pair is being published today in the journal Physical Review Letters (PRL). This major milestone, first reported by the CMS Collaboration in early April…

Can machine learning assist high-energy physics in discovering and characterising new particles? Physicists from the ATLAS, CMS and LHCb collaborations have just launched the TrackML challenge– your chance to develop new machine learning solutions…
