In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents.

A new independent measurement by the CMS experiment at the LHC is consistent with the existence of the most massive composite ...

A consortium of Boston-area researchers hopes to fill in a missing piece of a fundamental theory of physics within the next couple months, when groundbreaking tests are carried out at the world's ...

Luther College Physics Professor Todd Pedlar has received his seventh consecutive National Science Foundation (NSF) research grant. Since 2006, NSF grants have allowed Pedlar and Luther students to ...

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 ...

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 ...

First results from the Muon g-2 experiment at Fermilab have strengthened evidence of new physics. The centerpiece of the experiment is a 50-foot-diameter superconducting magnetic storage ring, which ...
