The CMS Collaboration hunts for Higgs bosons recoiling against dark matter particles
Dark matter is one of the most perplexing mysteries of our universe, accounting for roughly 27% of its total energy. Dark matter does not emit, absorb, or reflect…
By studying events with only a single energetic photon, the CMS experiment places some of the most stringent constraints to date on dark matter models and theories predicting extra dimensions of space.
One way to explore physics beyond the…
The CMS experiment conducts the first search for dark matter particles produced in association with an energetic narrow jet—the pencil jet.
Dark matter remains one of physics’ greatest mysteries. Despite making up about 27% of the universe’s…
The term "Dark Matter" was coined in 1933 by Fritz Zwicky. While studying the Coma galaxy cluster, he observed that the galaxies were moving too fast to be bound by the visible mass alone. He concluded that something else, something invisible…
A particle compatible with the Higgs boson of the standard model (SM) was observed in 2012 by the ATLAS and CMS Collaborations, with a mass of about 125 GeV. Could there be other heavier Higgs bosons, as predicted in some theories trying to…
The recent results from the Muon g-2 Collaboration have added to the growing tension between the measured and predicted values of the muon’s magnetic moment. The equivalent measurement of this property for the electron is a cornerstone of quantum…
