The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

The study of these fast-moving particles provides significant clues about the early universe.

In physical sciences, subatomic particles can be composite particles, such as the neutron and proton, or elementary particles. Based on the standard model, elementary particles are not made of other ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory.

GENEVA -- One of the very pillars of physics and Einstein's theory of relativity -- that nothing can go faster than the speed of light -- was rocked Thursday by new findings from one of the world's ...
