Particle Physics

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.

The discovery of two entangled quarks at the large Hadron Collider is the highest-energy observation of entanglement ever made.

The newly found antiparticle, called antihyperhydrogen-4, could have a potential imbalance with its matter counterpart that may help scientists understand how our universe came to be.

The elusive Higgs particle has the power to undo physics as we know it. The fact that it hasn't could have big implications about the nature of the universe.

Frank Close tells us about the history of particle physics, and what it means that charge in our universe's matter is so closely balanced.

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.
