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...

While the work on improvements on the detector continues during the Long Shutdown 2, physicists are starting to reap the rewards of the LHC dataset collected in LHC Run 2. The dataset is the largest sample ever collected at a collider and equivalent...

Since the discoveries of the third generation of quarks and leptons starting in the 1970s, physicists have asked the natural question "Can there be more generations?".  One of the first key results from the Large Electron Positron collider LEP...

Over the past century, physicists have developed a theory governing the fundamental interactions of elementary particles, known as the Standard Model of Particle Physics. Thus far, it has stood up to many experimental tests with an extraordinary...

The Standard Model of particle physics asserts that the Higgs boson generates the mass of all fundamental particles. In 2012 a new particle was discovered at the CERN LHC that behaves closely like the Higgs particle predicted by the Standard Model...

After the discovery of the Higgs boson, CMS observed its interaction with some standard model particles like the bottom and top quark, the tau lepton, and the W and Z boson.  Measuring the strength of interactions with quarks and leptons (called...

How long do fundamental particles live? In the Standard Model, we know particles can have many different lifetimes; from the top quark which decays in less than a millionth of a billionth of a billionth of a second, to stable particles like the...

The High-Luminosity LHC is a major upgrade of the Large Hadron Collider that is expected to increase the luminosity by a factor of 10 beyond the design luminosity of the current LHC. This means, the data produced per year will be equal to the amount...

In February, the CMS and MoEDAL collaborations at CERN signed an agreement to hand over to MoEDAL a section of the LHC beam pipe that was located inside CMS between 2008 and 2013. The delicate object, 6 metres long and made of beryllium, will now be...
