Latest Subatomic particles Stories
NOW that the euphoria and hype surrounding the search for the Higgs boson - using the Large Hadron Collider at Cern - have eased somewhat, it is perhaps opportune to raise a couple of important questions on the methodology of physical science, which seem to have been largely ignored or forgotten in the meantime.
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.
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.
