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, ...

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 ...

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 ...

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 ...

Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it charges up. The particle’s glow signals each step in its changing ...

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 ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

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 ...
