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...

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...

During LS2, CMS will install 144 additional muon detector modules specially designed to detect particles produced in the very forward region.    For the CMS experiment, Long Shutdown 2 (LS2) is like very prolonged open heart surgery. The main goal...

There is copious astrophysical and cosmological evidence for dark matter, but no indication of how it was produced, how it interacts with regular matter, or how it could fit into an inclusive model of particle physics. One possibility is that dark...
