"Precision in these measurements is critical, as even subtle discrepancies could signal deviations from the model — potentially revealing new physics." ...

For three decades, a riddle has followed neutrinos, the near-weightless particles that stream through Earth by the trillions each second. They change identities as they fly, shifting among three known ...

Scientists have made a particle physics discovery that they say could mean nothing less than the upheaval of our entire model of the building blocks of the universe—if their results can be ...

After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a ...

Just after the Tevatron collider at Fermilab in Illinois released its results, the Large Hadron Collider’s (LHC) ATLAS and CMS experiment teams presented their latest preliminary results in the search ...

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically ...

THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...

Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all. The first hints these elusive ...
