The Theoretical Advanced Study Institute in Elementary Particle Physics (TASI) recently concluded its 40th year, bringing 65 students from around the world to Boulder to delve into the “Frontiers of ...

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, ...

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

What if the Higgs boson found in 2012 is not alone but is the only sibling we have encountered so far? Scientists at CERN discovered the particle that year, and it was a major discovery because it ...

Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle and ...

A “muon shot” aims to study the basic forces of the cosmos. But meager federal budgets could limit its ambitions. By Dennis Overbye and Katrina Miller Friday, Dec. 8: This story was updated to include ...

A proposed funding program for small- and medium-scale projects reveals insights into the science, logistical challenges, and future of particle physics research. Particle physicists have a reputation ...

For decades, physicists searched for a missing piece of nature's puzzle, an elusive particle believed to explain why matter has mass. Nicknamed the "God particle", the Higgs boson became one of the ...

Here’s what you’ll learn when you read this story: It used to be thought that bizarre interactions between subatomic particles known as neutrinos could be explained by another type of neutrino. The ...
