Ultrasensitive experiments on trapped antiprotons provide a window onto possible differences between matter and antimatter. Now they could also shed light on the identity of dark matter.
Three physicists wanted to calculate how neutrinos change. They ended up discovering an unexpected relationship between some of the most ubiquitous objects in math.
In 1991, physicists, computer scientists, and a librarian at what is now SLAC National Accelerator Laboratory opened the first website in North America.
Data from the world’s most powerful particle colliders should shed light on a 100-year-old astrophysics mystery, but even they cannot explain the perplexing properties of the universe’s most energetic particles. Are ultra-high-energy cosmic rays heavier than expected?
The W boson mass is one of the fundamental ingredients that scientists use to calculate particle physics properties, such as the most likely mass of the soughtafter Higgs particle.
