Particle physics news, features and articles

Eight years ago, the International Space Station detected weird antimatter particles that challenge our entire understanding of physics. Now, researchers have proposed that mysterious cosmic "fireballs" could help explain the detection.

The physicist César Lattes, who is honored today (July 11) in a Google Doodle, is famous across Latin America for his discovery of the pion — a subatomic particle produced by shockwaves from exploding stars.

Celebrated theoretical physicist Peter Higgs, best known for predicting the existence of the Higgs boson, has died at the age of 94 after a short illness.

New theoretical research suggests that a mysterious form of matter called "unparticles" could be the driving force behind the expansion of the universe.

Scientists have created the world's first nanophotonic electron accelerator, which speeds negatively charged particles with mini laser pulses and is small enough to fit on a coin.

Scientists at the IceCube Neutrino Observatory have used 60,000 neutrinos to create the first map of the Milky Way made with matter and not light.

Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up.

By shining a strong beam of light through two chemical compounds, scientists discovered a unique new state of matter made of particles called excitons.

In the early universe, gravity may have been capable of creating light, a new theoretical paper finds.
