Weighted Z-photon(γ) mass distribution of events satisfying the H→Zγ selection in data. Events are weighted by the expected signal and background in a Zγ mass window containing 68% of the expected ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. When you purchase through links ...

This month marks the 10th anniversary of the discovery of the Higgs boson, a true “Holy Grail” of science that had eluded detection for almost 50 years. But what exactly is this particle, and why is ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

On July 4, 2012, scientists at CERN confirmed the observation of the Higgs boson, an elementary particle first proposed in the 1960s. The boson’s discovery was a momentous occasion, as it meant ...

Editor's Note: This story was updated at 7:20 p.m. E.T. For a subatomic particle that remained hidden for nearly 50 years, the Higgs boson is turning out to be remarkably well behaved. Yet more ...

“You can do it quickly, you can do it cheaply, or you can do it right. We did it right.” These were some of the opening remarks from David Toback, leader of the Collider Detector at Fermilab, as he ...

The Standard Model of Particle Physics has withstood rigorous test after test over many decades, and the discovery of the Higgs boson in 2012 provided the last observational piece of the puzzle. But ...

In the periodic table, no element is more important than another one. But in the Standard Model—a theory that explains the smallest constituents of the universe and the forces that govern them, minus ...

At a meeting held at CERN this morning, scientists presented the latest results from the search for the long-sought Higgs particle. After 30 years of research and $9 billion of investment, they’ve ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Ten years ago this week, two international collaborations of groups of scientists, including a large contingent from Caltech, confirmed that they had found conclusive evidence for the Higgs boson, an ...
