The CMS collaboration is presenting several new results at the 2019 European Society of Physics’s High-Energy Physics conference (EPS-HEP) taking place in Ghent, Belgium. The results cover a diverse assortment of topics and range from precision…

The CMS Collaboration has recently presented an updated search for new invisible particles. The technique capitalizes on the imbalance among the visible particles in a collision that such an object would induce. If dark matter is made of fundamental…

New physics may show up at the LHC in the form of yet unobserved particles which travel inside the detector before decaying, far from the point in space where they were produced. If these particles decay to photons, at CMS we can use the short but…

At the EPS-HEP conference this week the CMS collaboration presents new results of a powerful search that is motivated by a variety of new physics models that predict a signature of a bump in the production of the most frequently produced particles…

The CMS collaboration has recently released new results on how the top quark and Higgs boson interact, and this required a much deeper understanding of the production of top quarks together with bottom quarks.  The two heaviest known elementary…

Managing the amount of data from the Large Hadron Collider (LHC) collisions is a major challenge for CMS physicists. The detector produces more than 500 terabytes of data per second. Even after sophisticated real-time processing and filtering of the…

The study of dark matter is one of the primary research topics at the CMS experiment. The standard model of particle physics describes the behavior of elementary particles with incredible accuracy but provides no explanation or possible particle…

Paraskevas Sphicas, CMS' former co-Deputy Spokesperson of CMS (2014-2016), and CMS physics coordinator during the crucial phase from 2006 to the start of data taking, was elected as Fellow of the prestigious Royal Society of the UK and the…

After the LHC was shut down in December 2018 following the successful completion of RUN 2 operation, CMS is undergoing an intensive upgrade and maintenance program during the current two-year break (“Long Shutdown 2” or LS2) in order to ensure an…

This year, the CMS Data Analysis School (CMSDAS) celebrates a decade of hands-on trainings, exercises and challenges involving several hundreds of CMS members for the benefit of some 1500 students. Since 2010, the CMSDAS is designed to help CMS…

This year the 27th conference on Deep Inelastic Scattering and Related Subjects (DIS2019), is being held in Torino. As a part of the conference, the "Altarelli Prize" is awarded to a person with research experience in the fields covered by the DIS…

Physicists at the CMS experiment are now very close to observing the simultaneous production of four top quarks (really two top quarks and two antitop quarks, but particle physicists describe this process as tttt) at the Large Hadron Collider for…
