University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton. It was detected for the first time in a particle accelerator at Fermi National Accelerator Laboratory (Fermilab) in Illinois, Fermilab has announced. The heavy particle is scarce today, but scientists believe it was abundant soon after the Big Bang. "This discovery helps us understand how matter was formed in the universe. It shows the...

RIVERSIDE, Calif. -- What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? UC Riverside physicists are able to see for the first time in the laboratory that these atoms, which are called positronium atoms and are unstable by nature, become even more unstable after the collision. The positronium atoms are seen to destroy one another, turning into gamma radiation, a powerful type of electromagnetic radiation....
