WASHINGTON – Scientists have found an extra charming new subatomic particle that they hope will help further explain a key force that binds matter together.Physicists at the Large Hadron Collider in Europe announced Thursday the fleeting discovery of a long theorized but never-before-seen type of baryon.Baryons are subatomic particles made up of quarks. Protons and neutrons are the most common baryons. Quarks are even smaller particles that come in six types, two common types that are light and four heavier types.The high-speed collisions at the world's biggest atom smasher created for a fraction of a second a baryon particle called Xi cc, said Oxford physicist Guy Wilkinson, who is part of the experiment.The particle has two heavy quarks — both of a type that are called "charm"— and a light one. In the natural world, baryons have at most one heavy quark.
