by Lisa Grossman The Tevatron may now be defunct, but it is still detangling the nature of matter from beyond the grave. The late particle-smasher’s two main experiments, CDF and DZero, have released the most precise measurement yet of the mass of the W boson, one of the fundamental particles in the standard model of […]

ROGER DIXON gestures, bringing his hand alarmingly close to the big red button that has the power to shut down one of the world’s most powerful particle accelerators forever. “It’s already hooked up,” he says, in response to my nervous questions. We are standing in a room full of blinking displays and control panels at […]

by NELL GREENFIELDBOYCE On the grounds of a science laboratory near Chicago, a physicist named Dmitri Denisov walks up wooden steps to the top of something that looks sort of like an abandoned railroad bed. “Wow, look, it’s beautiful,” says Denisov, gazing out at a pond. “I didn’t even know about these flowers.” The tall mound […]

U.S.-based physicists said on Monday they hope to have enough data by the end of this month to establish if the elusive Higgs boson, a particle thought to have made the universe possible, exists in its long-predicted form. If the answer is no, scientists around the globe will have to rethink the 40-year-old Standard Model […]

A US particle machine has seen possible hints of the Higgs boson, it has emerged, after reports this week of similar glimpses at Europe’s Large Hadron Collider (LHC) laboratory. The Higgs boson sub-atomic particle is a missing cornerstone in the accepted theory of particle physics. Researchers have been analysing data from the Tevatron machine near […]

WHY the universe is filled with matter rather than antimatter is one of the great mysteries in physics. Now we are a step closer to understanding it, thanks to an experiment which creates more matter than antimatter, just like the early universe did. Our best understanding of the building blocks of matter and the forces […]

US particle physicists are inching closer to determining why the Universe exists in its current form, made overwhelmingly of matter. Physics suggests equal amounts of matter and antimatter should have been made in the Big Bang. In 2010, researchers at the Tevatron accelerator claimed preliminary results showing a small excess of matter over antimatter as […]

If physicists weren’t jumping up and down with excitement in April at the announcement that an unknown particle had been glimpsed at Fermilab, they are now. The news of a possible particle sighting in the debris of proton-antiproton collisions at the Illinois accelerator had been met with a mix of curiosity and scepticism. It was based on […]
