The particles and antiparticles of the Standard Model obey all sorts of conservation laws, with fundamental differences between fermionic particles and antiparticles and bosonic ones. The final piece ...

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 ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

New, precise measurements of already discovered particles are shaking up physics, according to a scientist working at the Large Hadron Collider. By Roger Jones / The Conversation Published May 9, 2022 ...

The Standard Model is the guiding light of particle physics. At its barest essence, the theory describes the 17 fundamental particles (six quarks, six leptons, and five bosons) that make up normal ...

Nobel laureate Chen Ning Yang, who spent decades advancing physics in both the U.S. and China, died in Beijing on Saturday at ...

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 ...

One of the best chances for proving beyond-the-standard-model physics relies on something called the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The standard model insists that the CKM matrix, which ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

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 ...
