An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

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 ...

A collaboration of hundreds of scientists have precisely measured the mass of the W boson, an elementary particle responsible for the weak nuclear force. The researchers found, to their surprise, that ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

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 ...

The muon’s mysteries continue to leave physicists spellbound. Last year, an experiment suggested that the elementary particle had inexplicably strong magnetism, possibly breaking a decades-long streak ...

For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons. While the past few decades have produced some compelling candidates, ...
