On July 4, 2012, researchers at the Large Hadron Collider (LHC) in Switzerland announced with great fanfare that they had successfully detected the Higgs boson, the manifestation of the mechanism that ...

Every few years, scientists take a step back to take a broader look at their field and determine what questions are most pressing—and what tools they will need to answer those questions. This year the ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Here’s what you’ll learn when you read this story: For nearly a century, the magnetic anomaly of the fundamental particle known as a muon has served as a means to test theories against experimental ...

Physicists were left with more questions than answers this week after returning empty-handed following a painstaking search for an elusive theoretical particle called a sterile neutrino. The results ...

Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found ...
